Don't try and contact MTN on their "customer care" line

MTN contacted me for a phone /contract renewal and upgrade and the sales person was great. Things have gone downhill due to MTN's policy on deliveries. I made the mistake of failing to tell the sasles person that my ID book had been ******. Apparently their couriers DSV are instructed to only deliver on presentation of the original book/card and a copy and a driver's license is not acceptable. I have been a customer for 25 years and at the same business address for 14 years. I have a driver's license and a copy of my ****** ID book. This wasn't good enough for DSC who have no fall back position when told the original ID is not available. I was referred back to MTN's customer care line. This number is anything but caring. After 50 minutes I had not managed to speak to anyone who could assist me. A second attempt the next day did not get past the automated menu stage. An email to customer care got a response in the form of a request for my ID number which i supp****. No response yet. I realize I am one of millions of subscribers, but there has to be a better way to manage customer interactions than the despicably bad help line.
