I just don't understand how they can just randomly decide how much to charge without me knowing, they advertise £2.50 a month, happy to pay them that and no more - £10 tops... £230 is a bit much really!

Why would you be happy to pay them £10? Why would you pay them anything if you're not their customer?
Seems utterly bizzare to me that you'd be able to get yourself into a situation where a company has an account and direct debit in your name and you'd not know about it.
