*****ing our customers data

Will never upgrade with MTN again. When I did upgrade nobody told me that MTN would be *****ing my left over data. Previous contract would carry over. Now on new contract, MTN carries unused minutes over to the following month, but my left over data is not. They ***** it from customers. I pay for the 500mg data and they ***** it from me what is left over. MTN is robbing customers. Vodacom does not do that, they carry your data over to the following month. Terrible customer service from MTN. Wont upgrade with you again, nor will I upgrade the other 2 extra numbers I have when contracts are over.
