Autopage overchargin

Since last year I have been asking Autopage to check my account because I have been billed additional data when I should have been getting a 5gb on my red Vip plan. I have logged serval complaints online and instore and I have never received feedback, what kind of service is this, I spend 2000 a month with Autopage and no one has the curtacy to call be back, instead they block my line. I have had it with auto pages service. If no one gets back to me I will be gorcced to get my lawyers involed. R10 000 was taken off my account this month and this is after I contacted Autopage advises them that they billing is incorrect and that my data has had issues since last year and till this day I have been paying but the issues haven't been resolved. I'm sick and tired of Autopage,seriously catch a wake up!!
