Okay, here's the situation:
I entered into a 24 month mobile broadband contract with 3 in April 2009 (commencing May 2009).
In January 2011 I moved into a new house with broadband already connected, as such the 3 broadband package was now superfluous to my needs (and at any rate had been utterly useless throughout). However, aware that I was on a 24 month contract I waited until May 2011 to cancel it.
According to 3's own T&Cs a contract can be cancelled at any point after it has elapsed and this can be done in writing or over the telephone. I called 3 in May and requested the contract be cancelled. I thought that would be the end of the matter, but in June a payment left my account. I telephoned them again and spoke to a customer services guy again who assured me that the situation would be resolved, but in July another payment left my account. Several more telephone calls failed to settle the matter so I went to Natwest and cancelled the Direct Debit.
Evere since I have had at least one and often multiple telephone calls from 3 on a daily basis. They refuse to be able to grasp the fact that my contract has elapsed and that my attempt to cancel the contract got me nowhere.
Now, they have written to me threatening court action, warning me that my credit rating will suffer and in one phone call threatened that they would shut my mobile phone (also on a separate 3 contract) down, in spite of the fact that I'm happy with that service and am making my payments for it without fail.
Has anyone else experienced similar difficulties with 3 (or any other company for that matter), what practical advice do you have for me?
Any help gratefully received!
