Re: WalkWalk
I'm still waiting for a call back with contact details for a UK-based manager that I can talk to - since asking for it in November, though ......
No problem, they are over eight weeks and complaint is not resolved, you can refer your complaint to the Communications Ombudsman, whether W*nkW*nk like it or not:

Simply by taking the complaint up for investigation, W*nkW*nk will be charged a case fee of around £400. They'll probably find in your favour - you won't get much by way of compensation, but you'll have your complaint resolved, and you are not exposed to any risk of paying their costs regardless of the outcome, so hit them where it hurts.
The same organisation (as the Energy Ombudsman) and broadly similar rules applies to energy suppliers, so any unhappy energy customers should do the same. You can complain before the eight weeks, but to do that you have to have what's called a "deadlock letter", where the company admit that you and they cannot agree - getting one of those out of an under-performing company is like getting blood out of a stone.
