Pathetic, pathetic service from 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.... It still remains the responsabillity of MTN to get this issue resolved, they are the ones contracting out to Rewardsco..... Come on MTN this is your name at stake here......
