I have had months of problems with this disgusting company, fed up with them not replying to emails, not replying to letters, and the only way to contact these people is by ringing their 0844 number they tell everyone to ring, their policy is to delay everything, you cant contact them, they just delay all the angry customers while they continue to take money each month for service agreements.
call them on these freephone numbers, just ask to be put through to whoever you want, if they say they cant them just ring back until they do,
0800 023 4701
0800 587 8787
their legal dept if you want to threaten them with court action - 01727 202030
and finally, as they never seem to reply to emails, just email their CEO - sebastian james, i am not allowed to post email addresses, but perhaps someone with more than 10 posts can post up his email, but to work it out - sebastian.james then followed by @dixons.co.uk
