Excessive account!

<br> I got a R2600 cellphone bill! My average spent on a monthly basis is R350 and my bill has never been over R500. So you can imagine my surprise and shock when I receive this account. In the month prier to the bill I got a sms saying that I have now reached my credit limit and that my service has been suspended. This was surprising to me as well and when I phoned in, the person on the other side said, that I don't have to worry since my bill is only R400 odd and he doesn't understand why I got this sms. I was then reconnected.<br> <br> Then 2 week later I got this R2600 bill. R1700 of it for data spend. I tried to phone the MTN helpline on numerous occasions for assistance but nobody answers. Got through once and the person on the line said they will send me a URL listing to see what websites were used. This was a month ago and I haven't received any correspondence from MTN.<br> <br> This is pathetic service! Apparently MTN is on a strike and I assume this is the reason for the delay, but still... Pathetic! How can they just charge me more than 5 times my normal bill and then don't respond to any queries I have???
