MTN de*****s customer of data which was purchased???

Purchased 5GB of data on Sun morning off the MTN online portal, paid by credit card and loaded the data on the online portal by inserting sim allocated tel no. Well the data sim to date has not worked, spent countless FB messages and calls to the MTN online support, which i must add is useless!!! Was then advised the sim card had an issue and was told to purchase another one which I did, I was told to forward the sim details with proof of data purchase to: ***, The reference number is ***. Have had ZERO communication, and all my further FB messenger support requests are read, but are not responded to??? MTN, you should be ashamed of your ********** business ethics. Will refer this to ICASA and CPA
