Poor Service

<p>on the13 April I have upgrade my contract with mtn, I have chose to renew my upgrade because I considered mtn to be a good service provider as my previous service providers gave me a lot of hassles, however my newly upgraded phone was giving me problems so I took it to the Brooklyn store in Pretoria on 24 May 2016, i have not received any confirmation / tracking messages about my phones that is gone in for repairs on the number that i have given for contact. i am very unhappy with the service that i am receiving and i decided to call the mtn repair center after many many calls to them, the consultant told me that my warranty assessment was approved there i am sittn with no phone and waitng for someone from mtn to call me, i sent many emails and tried calling and not getting any response but i had to do their job myself, which i am payn them for. please look into this horrible service. i have still not got any response and sitting without a phone and mtn contact store numbers are useless you cant get throught any, very frustrated. please help</p> <p> </p>
