two weeks ago my broadband went down after that bt dropped my ip, speed was at 244 never going up or down as previously it was 290 to 310 download, the people asked about my equpment I said i had changed filters, they suggested maybe my router maybe at fault, so I brought a new router filter etc speed went to a constant 260 done a bt test told tech support they said i should be a lot higher etc they said they would get in touch with bt with in two days my speed went up to 710 download and is at moment constant, the people at support never asked me silly q or treated me as an idiot,and said if this goes wrong with in two weeks would just re open with out going through new tests and q, which is good.
treatment has been friendly and positive, and did not fob me off,
as others said price is high but for what you get worth it.
