Poor service from MTN

I bought data via the MTN app using my bank. I receiveda receipt from mtn confirming my purchase. It's now 3 days and the data has not been loaded and every time I call, a new ticket is being opened. I'm sent from pillar to post. Every time I ask for a supervisor or manager, I'm told they are in a meeting. I even called my bank to check with them and i was told the money went through to mtn. Today is the 3rd day since I bought the data and now I'm told I have to wait for 7 days for the issue to be resolved! Why would I buy data now and be forced to wait for 7 days to use it??? I curse the day I changed from vodacom to give mtn a change, mtn is super useless!!!!
