What a relief to find this thread.
I also have been getting threatening letters from Roxburghe and their pet-solicitors, Graham White, concerning a debt that Pipex told me was settled over 2 and a half years ago. I rang them 3 times but got nowhere.
I am due to see the doctor on Monday as I am dead on my feet. due to being unable to sleep properly. When I try to sleep I just get phrases from the letters and things I am planning to say in court whirring through my head. I have to be absolutely exhausted to be able to drop off.
This is partly due to the appalling treatment I got from Pipex during the original dispute where the cut off my internet for 5 weeks after telling me the only people who could deal with the case had no phone number - and then ignored my letters. I start to quiver with anger slightly even now, when I thin about it.
Thank you Conmankiller, I have sent a copy of the letter you provided to Roxburghe (with the missing word in paragraph 3 added) recorded delivery.
I think I may be able to sleep tonight.
