MTN *****S MONEY from CLIENTS

22 Years I have been a client with MTN. I have two account with them the one account i could do an upgrade end of April but chose not to because my son is suppose to take out his own contract. So MTN has thought is good to without prior arrangement or communicating if with me that they will just charge me R120 per month more for this contract that was not upgraded, with no extra service of course. For a company that specializes in COMMUNICATION they have no clue.
