MTN customer dissatisfaction

This is not the first time that I have experienced terrible service from the Cape Gate MTN Franchise. I tried to cancel or upgrade an existing data contract (***) for the last 2 months but to no avail. I am told that the contract is blocked by an unfinished telephonic process and there is nothing that they can do. I try to avoid telesales as far as possible because most of the times the background noise is so loud that you cannot hear what is being said and if you ask for an email detailing the information it is just ignored. If any person has information how to make MTN a customer orientated company it would be appreciated. I would further recommend that franchises that represent MTN but is not willing to help customers with MTN related problems should be closed.
