Pathetic Service

It's been almost a week and I have had no response regarding what I should do! I am paying for a phone which I cannot make use off and there is no way I can be assisted as everytime my phone gets sent it its always a case of software... The pathetic service I have been receiving from mtn is a disgrace to the company... I will surely cancel all my contracts to save myself from such Bad Service and would never recommend anyone to do business with MTN as their Aftersales is the worst because they don't give a damn about their Loyal customers!!!
