Pathetic service from Rewardsco and MTN

Have requested an upgrade on my MTN contract through Rewardsco..... I changed my mind about the phone I want (never received the phone, so upgrade was not activated yet) Now I jave been waiting for 6 weeks to het this upgrade request cancelled so that I can do the new upgrade. Pathetic service..... I only get a response that the matter has been escalated to management for urgent resolution.....how urgent is it if it takes 6 weeks...... I will never use MTN online shop again!!!!! An I am considering moving to another cellphone service provider company, as MTN is of no assistance whatsoever....
