No proper assistance, and left to pay for it.

I am travelling overseas. Before I left, I visited the MTN branch in Randridge Mall. I asked about setting up roaming and keeping my number (as a prepaid user). They simply said that it will all work and nothing needed to be done, and they did nothing. Overseas, my roaming never worked. I couldn’t send any texts or keep my number active, and couldn’t get proper help for this. I lost my number. I was later told that I should’ve been given number for life. Without that original number, I cannot reactivate my banking app and am stuck. I have to pay to get a ****le couriered, so that I can access my banking. I am left struggling and having to pay out a lot of money, because MTN employees 1) don’t care or 2) don’t have any proper training.
