Hi, I need to know how to proceed. I have signed up with a competitive internet/phone co. and set up a direct debit with them. Every month I am overcharged. Every month I email them and ring them, complainly nicely about the overcharging. They always agree with me and promise that by the next billing correction will be made, and that I will be credited for the overcharging of previous months. I continue to be overcharged. I am in contact with different people every time. They are always very polite and sympathetic, but actually not very helpful, as my billing still hasn't changed. What should I do now? Thank you.
