Well, a tricky one.
They want me to pay for an engineer that went out to fix a line when the cause of the problem was a third party.
I refuse to...
It would be a shame to fall out with them - we would need to sort hundreds of lines that are with them.
Maybe we need to talk to some other LLU providers - perhaps Virgin or TalkTalk.
Lets hope they see sense.
P.S. Of course the answer may be we pay but never sell another line with them ever... That is their choice.
P.P.S. This is a case where the fault was not caused by customer equipment. A case where even BT would not charge us. An interference issue from a third party.
