I am writing on behalf of my neighbour, who is having an issue with a recent (talktalk) phone bill.
The last phone bill that came through showed up as charging around £80 for a single call, which had apparently lasted hours. I suspect that the problem is that the phone reciever (his end) was not properly replaced, even though the reciever at the other end was.
Does anybody have any advice for disputing this charge? Is there any way of proving that the person at the other end had put the phone down?
