Well that's just great news!
I hate dealing with BT... the fact that wherever I buy from then provide the backbone to my landline and fibre broadband service because I live in an area where there are no alternatives (unless I want to add a layer of complexity when things break). The fact BT insist on charging me extra because I refuse to pay by direct debit when they won't give me a chance to see my bill before they take my money if I do.
I switched my mobile service from Vodafone to EE in the spring to improve my 3G coverage and get a decent 4G service; I've always avoided O2 because of their past connections with BT and 3 just weren't cutting it in my area.
Now I have the displeasure that I will be giving more of my hard earned to BT for at least the remainder of my 2 year contract. After that?
Do not pass go. Do not collect £200.
