INCORRECT BILLING FOR THREE MONTHS

I really dislike, NO I hate this network ever since I took a contract with them. I have been billed incorrectly for ****** three months, my bill in February is R 2607.34, January was R4304.38 and in December was R 3434.97. The thing that frustrates me the most is that I buy my own data bundles but still have to pay so much. I have queried but no one was able assist me. I will never recommend anyone to take a contract with MTN. I really need my money back you have made my life so difficult.<br> <br> E***
