Telkom Wont Stop *****ing My Money

2 Years ago I took out a cell phone contract costing me R174 flat fee per month, I had no problem until I needed to upgrade, I upgraded to a R199 flat fee per month contract. Firstly Telkom politely deactivated my sim card from my old contract without sending me the new one, after fighting for 2 weeks I eventually receive my new sim card. Then came my first debit order of my new contract which was supposed to be R199, instead R726, I phoned Telkom immediately, they told me that I have an ADD On Data Bundle of R418 on my account and a pro rate amount of R118 for two weeks (even though Telkom did don't send me a sim card for my upgraded contract but still charged pro rata amount for it)<br> They then opened a case to have this problem rectified, somebody contacted me 7 working days later and informed me that The data bundle will be removed as I did not request it and they will credit my account until I have recouped the money that was incorrectly billed, one month later I received another debit order of R557, I phoned Telkom again and again and again, and again, nobody from customer care can help me! I CANT AFFORD THIS I HAVE A CHILD TO FEED!!!PLEASE HELP!!!
