MTN is worst than South african postal service on client service

I Open a new account for a phone online after i was advised by MTN stores in Hoedspruit and Tzaneen that it will be faster to get the phone due to the rots One I have the new phone and sim I can port my existing number from Cel C to MTN as long as I have not activated the sim. After many month many phone calls and visits to various mtn store I have little success . I a sim that is still as I received I am still using Cell C and are paying for an acount that I am not ussing with nobody from MTN even truing to assist me. If i knew back then what poor service I would have got from MTN I would havre rather use our south African postal services as their service delivery is 5 star compare to MTN. Even as I write this review I have little hope for assistance from them all I can do is stop all payments and keep the money in my savings account on all my accounts until MTN can deliver a service
