Inconvenienced by the MTN

I began the process of taking up a MTN contract at the store in Pavilion Durban. I went there on a Sunday and needless to say i am sitting now in a situation were i cannot use my old cell number or the new one because of the incompetence of MTN. The consultant in the store told me that they cannot port my number the same day, because it is a Sunday, and that i need to do it another day- this extremely poor customer service. Then i call customer service and i am told i must purchase a prepaid sim card, wait a few weeks and then the number will port. now today i find out that the number cannot port because the consultant in the store activated the MTN contract sim. What an ABSOLUTE disaster. I am now calling and emailing trying to get someone to rectify the incompetence of the store consultant and the customer service department. The consultant at the store clearly was more interested in meeting his own targets than meeting my requirements, he has inconvenienced me in so many ways, Does MTN understand what a lengthy process it is to update a cell number to every person, institute and work? I am absolutely flabbergasted by the lack of customer service. I urge MTN to contact me as soon as possible to sort this out, I came to MTN because i thought it was a good service provider and better options, now i am regretting my decision. I dont need excuses from agents, but i need a solution and i would like one as soon as possible!
