lodge a query with my account

My phone got blocked. after struggling two days to get through to customer care, with no luck, I went in to a MTN store to ask why my phone is blocked. was told my account is over my set limit. that was strange as my limit is R1500 and I have never got to that amount in the time I had my phone.<br> I was told to phone the customer services, but could not get through at all. After numerous attemps, and holding on for 45min to a hour at a time I finaly got through to a lady at MTN on the 18 June, I told her my problem and she advised that my data usage was over R1800.00. How much do you need to download to use so much data.<br> I have a wifi at home so evenings and weekends I log onto my wifi and I don't use my data at all.<br> She said that she logged a complaint and that someone will contact me and then they will investigate the data usage on my phone.<br> till date no one has phone me or sent a sms to say that they busy with it. I had to pay the ridiculous amount of R2900.00 this month and I don't have any cer*****y if anyone is looking into the situation.<br> I am very disappointed as the customer services and accessibility of MTN is very poor.
