I have had TalkTalk for years and I can honestly say that I have no serious complaints - and therefore no comments about customer services because I have very rarely needed them. Yes, at times the service seems slow or slower, but from reading other provider reviews that seems a common problem. There have been three users in this house, one who has used the service for a part-time interest in DJ'ing, one who has done extensive university work online as well as played games, and myself, an "average" user: TalkTalk has not caused us any problems with simultaneous usage. (My only trivial moan is that, whenever they offer me a new contract, it is always more than my current one (that appears to have no end date anyway!).
