Payment charges and basic lines
As well as the increase in charges, BT needs to be slapped down over the payment processing fee, which is £6 per bill at the moment. They used to say it's for paying by cheque, but actually it covers everything except direct debit, and there's no justification at all to charge for people who are paying by internet banking, for instance.
Over the many years of incompetence I've endured from BT - especially when I had an ISDN2 line - they've overbilled, sometimes by hundreds of pounds, so there's no way I'm ever going to give them instant access to my account, yet they choose to penalise me for it anyway.
Their last bill change, suddenly charging many people for caller ID who had previously had it free, was poorly communicated, and this latest one is about the final straw - I'm waiting for an unbundled VDSL service, and when that comes to my corner cabinet, the landline will be unbundled from BT too.
Really, Ofcom should force them to provide a 'line only' service for DSL subscribers who don't want a dialtone. My latest bill is £57 for a quarter; £4 of that is rent for the burglar alarm that is plugged into it, which I'll happily replace. The rest is just rental, for a line that I don't use for anything else, and could easily do without - its sole purpose is to carry the DSL, and with it my SIP trunks. With the 'payment processing' charge, this is getting on for not much short of £20 a month for the copper wire, because of their bundling in things I don't need or use, like evening and weekend calls.
