Data bundle not received causing ridiculous bill

After numerous phone calls to change my monthly 500 mb data bundle to 1 gb. I received the 1 gb data bundle in the month after I made this request, so to my knowledge this was sorted out. I received a sms this month showing that my account has increased seven fold, because somehow I did not get my monthly 1 gb data bundle.<br> <br> After over 8 phone calls to Autopage (head office and Worcester branch) my account issues have still not been sorted out. Autopage head office has hung up on me several times and has not returned my phone calls as promised. I have also sent four emails to them, with no legitimate response as to how they are going to sort out this issue.<br> <br> If this issue is not sorted out as soon as possible, I WILL stop my debit order as I refuse to pay this obscene amount of money for an error made by Autopage.<br>
