Contract and feedback

For 4 months Auto page management said they will call me back within 2 to 3 days and NO one did. The contract that i signed for and what auto page bill me for is not the same. My contract is as follow - R999 for my Infinite Plan (10G of data and unlimited calls and sms's) and R600 for my device and both my insurance (sim and device). In total i must pay R1600 p/m for my contract , auto page charge me R1700 for my monthly cost also they charge me for calls and sms's that i have unlimited of but still have to pay for that and they charge me for my device. I'M NOT GOING TO PAY MY CONTRACT UNLESS AUTO PAGE MANAGEMENT CALLS ME BACK SO WE CAN SORT THIS OUT.
