Mtn the worst service provider

25 September 2015 i upgraded to a Samsung S6 after updating software phone started having freezing problems to an extend that the phone switched off even though the battery was full. Returned phone to mtn n it was booked in for a warranty assessment n due to the phone having a dent the assessment was rejected. Instead of booking phone for repair they returned it after 2wks. Had to call in myself a couple of times to check for feedback since they never contacted me since<br> taking the phone. Went to store to collect phone today and some accesories missing in the box, now phone has to be returned to the repair centre so they can put back missing items which will again take 2wks before receiving phone bck. This means that i am paying for a phone that i do not have and again do not understand why an assessment was not done as the dent on the phone has nothing to do with software issues. As a valued customer i do not accept to wait that long for a minor issue to be resolved. I then requested a settlement amount and once again i get questions thrown at me as to why ive taken the decision and not what i have requested. Am so dissapointed that i am gonna buy out of the contract. Bad service
