Changed my tariff today to one that's the same price but was better value. Its a 30 day rolling contract. Checked my online account and it says I'm loads outside of my tariff now! I'm going to cancel my contract if they try to take that out of my account! I don't use my phone that much!
I've just called them and apparently I've got to wait 48hrs to find out how or why I've incurred this charge! I've been through my usage page by page and I can't find any instance when I've used my phone outside of my tariff once so I can only put it down to my changeover earlier. I'm very, very annoyed about this and I've told them if they try to take this money out of my account I'm going to cancel my contract! It's not fair when I wasn't informed of any charges when I spoke to someone earlier :-(
