Very Bad Service while trying to buy an Apple Xs

Context: there was ********** activity at MTN afew years back & I sent MTN all the documents and it was sorted Now I have app**** for a contract at an apple store mall of Africa last mid-week and the MTN portal instore says I have a ***** status I must provide a letter from “MTN” legal to “MTN instore portal”. I call MTN many many times, I have recived many notifications sms saying my query is resolved, till now I cant move because MTN is unable to get a document from their internal people. Different agents tell me different things. The question is, if MTN is giving me such sh#ty service when I am trying to BUY from them, what is going to happen when I have to be service. Its been plus 8 days now and I am seriously thing of getting the apple Xs from Vodacom. I have more than 10 “Your query has been resolved” SMSes
