Totally not impressed

Hi<br> <br> I upgraded in April and took a modem. 3GB and requested that it must be a top up. I only started using the modem and sim in September. My bill has always been R189 because I wasnt using the device. To my surprise an amount of R2130 was deducted yesterday. I called 808 and was informed it was the data. I was very confused because I asked for a top up, all my current and previous contracts are also top up. Apparently a limitless data was loaded on my account. I then asked them to update it. I went to the MTN in Alberton and got the best service ever, they showed me my account history and it shows that I recently started using the device and a limit was not loaded from the time I took it. I called MTN Melrose and Winki was on leave. I went there today and what an attitude I got from here different from Alberton. She firstly made it seem like im lying, theres no way I havent been using the device. Secondly, she couldnt check my history because systems are different and she needs to log it. Thirdly, she advises me to go and REVERSE the transaction so I can get my money. So in doing that my account will eventually be in arrears! Then she says MTN will not reimburse me they will credi
