TERRIBLE Customer service

Someone called me in June to upgrade my contacts. I upgraded 2 lines to the same package. The one line I get everything as agreed the other I am not receiving my minutes of data yet the line has been upgraded. I have spent over a month trying to get hold of ANYONE at MTN who can help me. I have sent an email to complaints and was told I would receive a response in 14 days. No response. Your call centre is TERRIBLE. More than half the people working from home do not even have the facilities to be able to work from home. Their internet connection is so bad they cant hear you and you are just transferred from person to person. The managers are ALWAYS in meetings and no one returns your calls or messages left for them. The actual branch is not willing to assist as it was an online upgrade. I am DEFEATED!!!! And the sad thing is I was ready to jump ship and move my business to Telkom and this amazing offer was sold to me. NOW I AM STUCK and no one can assist.
