Disgusting service from MTN

I have had absolutely no internet access from MTN for 6 days now, despite numerous emails to them explaining the problem. This is beyond belief. All I get is an automated response with a reference number ... if I re-send, I get another reference number!!! The original reference was the following (which is presumably, at their end, attached to my original email). I am desperate for service! e9aa0e61-90fe-4deb-92a1-558886c8d877
