No connectivity on the MTN network during load shedding (particularly in Kyalami)

I'm disappointed that MTN has failed to make the necessary investment to its infrastructure like its competitors to keep customers connected consistently, notwithstanding the extreme load shedding siege the country is under. If, during load shedding, I don't have WiFi access from another source, my MTN contract is as good as useless as I'm unable to use my MTN data or airtime to stay connected. I've called the call centre on numerous occasions and the response has been to simply remove my SIM card and to try again. It's so disheartening to know that there's no other solution than to vote with my feet and to move to a competitor after more than two decades of loyalty.
