Getting through to Carphone Warehouse
Lardboy has my sympathies. I am a Onetel customer now a Talk Talk / Carphone Warehouse customer. When I moved house they completely messed up moving my phone and it was impossible to get through to anyone who had the remotest idea that they should try to put it right.
So I looked up their website (they're also known as Opal Telecom) and found a) an organisation chart with some useful names and b) various phone numbers for their head office. So I called their credit control number (always a good one to try as most companies are greedy enough to publish it and answer it promptly) and played dumb saying I must have dialled the wrong number, could I speak to Steve Rescoria who was (if I remember correctly) their director of customer service - amazingly I was put straight through (his direct line then, I found out, was 01925 554621) and he got one of his team John Mitchell (01925 554369) to deal with it. After some time a very helpful lady in their "Chairman's Office" (aka an upmarket call centre dealing with difficult punters like me) entered into negotiations and I ended up accepting fifty quid - less than I wanted but I was happy to settle having got them to agree to the principle of compensating me.
So it's worth persevering and being devious. And yes, had they not negotiated it would have been the County Court.
