WRONG BILLING

In March i signed an MTN contract at the IStore Sandton,for an Ipad Mini.. Monthly repayment R. 279.00 a month , for 2 months the billing was correct. Now in June i have been billed. ZAR. 1,944.00 Came in June when i received the statement i query with the lady who help me with contract, who promised that the statement was n wrong and that she will sort this out for me, t This morning ZAR. 1,944.00 was taken out of my account , this is unfair when you sign a contract and now you are billed what you didn't signed for or used. All i need is my money back no excuses or credits.<br> <br> Kindly sort this our with who ever made the mistake<br> <br> thank you<br> <br> Kind regards<br> <br> Dorothy
