Orange issued distributors with three separate do not deal notices a fortnight ago and another three last week.
Each do not deal notice relates to stockists that employ outbound call centres to sell Orange stock.
An Orange spokesperson said:
"Having received and reviewed a number of customer complaints we have ceased trading with six channel partners.
"The customer experience and care offered by their outbound call centres was unacceptable. As a consequence do not deal notices have been issued to our distribution channel. The review is ongoing."
Orange along with T-Mobile also set out strict guidelines for outbound call centres this week (see story page 2).
In an e-mail to its channel partners this week it said outbound call centres must record all calls so Orange can audit them. It also stated that scripts must be checked and approved by Orange and that call centres must identify themselves and state that they are not acting on behalf of Orange.
It also issued new guidelines for outbound texting. Outbound text messages must be approved by Orange and text messages must identify the third party and include a web address where full details of the offer can be found.
The e-mail stated: "Failure to comply with the procedures above will result in suspension and or termination of your Orange dealer code. All existing call centres must have their current scripts approved and with a change of campaign all new scripts must also be approved."

A source close to the company said that the group was hoping to enter the Chinese mobile market as early as this August and that the likely collaborator in the project is China Unicom which currently has 150 million customers.

Branson accused the country´s three existing mobile phone networks of ripping off 80 per cent of the French population.
Telephony services will be provided by Orange which came on board after the three existing French networks were fined for collusion by the EU.
The new MVNO offers unlimited texting 24 hours a day seven days a week.
"In France the existing operators defend their interests and consumers have lost confidence in them" said Branson. "We want an operator that doesn´t work against customers but with them."
Branson was unable to comment on whether the French text deal would be extended to UK customers.

"It is vital that we have the best support as the first BenQ-Siemens branded handsets are launched in the UK" said BenQ Mobile UK and Ireland managing director Philip Rambech.

To attend the fans were instructed to go to Waterloo station in London where they received a Bluetooth message promoting the gig.
The venue also featured a demo room where the media could try out the new handsets which were pre-loaded with exclusive music content.
"Bluetooth is the ideal democratic vehicle for Dirty Pretty Things" said Mercury Records president Jason Iley. "Anything that brings together a band and its fans is fine by me."

O2 has been 3´s roaming partner since 3 launched in 2003. 3 invited UK networks to tender for the roaming contract 18 months ago and the network said Orange tendered the most competitive bid.
3 UK CEO Bob Fuller said: "It was important we had a competitive tender and I am delighted with the outcome of the process. This is a good agreement for both 3 and Orange and will ensure that we continue to offer a great service to our customers."
An O2 spokesman said: "We weren´t prepared to win at any cost. Our bid was based on a sound commercial proposition and we weren´t prepared to go above our valuation. You have to set a price that you think is realistic and stick to it."
He added: "We will continue to benefit for some time until all of the roaming traffic can be migrated away from our network next year."
3 has continued to roll out its network and now claims to have 88 per cent population coverage. At the same time subscriber numbers have grown to 3.5 million. Orange claims 99 per cent population coverage.

The Web´n´Walk deal encourages mobile users on to the Internet for a flat rate of £17 a month with a new Web´n´Walk datacard.
"We believe that broadband mobile will change the way we work live and play more even than mobile voice has done" said T-Mobile sales director Simon Ainslie.
"We have led the way with open internet access for mobile and with speeds that already well exceed dial-up. Later this year we will launch true broadband mobile speeds."
Web´n´Walk Professional potentially offers users Internet access at speeds six times faster than 3G. The card is also quad-band allowing users to roam in more countries including the US.
"In the past people were worried about how long they were using the Internet on their phone" added Shaw. "This plan means that is no longer a consideration. I think in time it will become the norm in the same way broadband did."
Ainslie added: "Until today cost has been a barrier to customer take-up. Now Web´n´Walk Professional makes Internet access on the move a reality. "

A Phones 4U spokesman revealed the sale was "progressing well" but refused to be drawn on details of the contenders. He did confirm that "a winner is expected to be announced within a month".

Owner John Caudwell sold Caudwell Communications the fixed-line service that trades as Homecall to telecoms group Pipex in March.
However the sale of the rest of the group which includes high street retailer Phones 4U and logistics business Dextra could still fall through if a price cannot be agreed.
Caudwell believes his business to be worth over £1 billion but the private equity groups are thought to be pitching bids below this sum.
