Shocked at the incompetence of MTN

I had the misfortune of dealing with Lwazi from the 137 MTN call center after waiting for more than 10 minutes i was transferred to him, I was calling on behalf of my 67 year old neighbour who had been barred from recharging for 24hrs after repeated failed attempts to input the voucher number, bearing in mind he will be traveling 6hrs this evening to East London....without being able to call anybody heaven forbid something should happen along the way...Lwazi explained that the voucher had indeed been used on my neighbors phone, my next query was what is using up his airtime as he informed me that he had not made any calls, trying to resolve what causes his airtime to literally dissapear... i was abruptly told by Lwazi that i should phone back after 2hrs as he cannot log two queries at once and he cut the call as i was still asking why is this so.....OMW really MTN with the technology we have today are you guys still stuck in the dark ages? And a course on manners to your center agents should be mandatory!
