Ridiculous data invoices for the last few months

<p>My account in July and August for data was ridiculous. I have never ever gone over my amount and MTN cannot stop your account if you go over. I had to take put a contract. It is absolutely nonsense and I would like a full report on why my account have been so high???? R8800.00 in July and R7300.00 in August. I am scared to look at my September account. I cannot get an explanation on exactly what data was used and how it happened. I do not have R15 0000.00 for my account for 2 months and I am desperate.....as far as I am concerned it is absolute abuse and when a friend phoned they said my account was linked to a Telcom account. How is his possible????..</p>
