MTN doesn't care especially when they already have your money

Ordered an uncapped data deal online. Had to do an immediate upfront double payment. DSV tried to deliver twice. Kept giving technical error on fingerprint reader for MTN verification. Called DSV but they said MTN needs to fix the problem. Phoned MTN, every department put me through to the next carried on like this for an hour until I gave up. Sent an email and got a reply someone would assist me shortly. 2 days later and still no answers or response. Paid upfront for something I can't get and MTN doesn't help what so ever.
