Terrible service from mtn direct...ridiculous

I did an online application a week ago and a consultant called me to request documents. I have sent through those documents and it was a whole week with no reponse. I called mtn direct twice to follow up with both times the consultant saying they will get someone to call me back. When i called the third time to follow up the lady say my iD is blocked. I asked them why and they cannot me a response. So i queried as to why nobody contacted me to let me know. She said she cannot tell me why. I need to go to a store?! If i wanted to go to the store why would i call mtn direct? So i am still looking for answers and at the same time still cannot do a contract application. Is this how mtn treat new customers?
