WORST SERVICE IN SOUTH AFRICA

MTN has the worst customer service in South Africa.I went to the store to do a sim swap to do sim swap because my phone was ******.i was informed that the number is blocked and a ticket was logged and informed that it will be resolved within 48hours.the 48 hours passed and my number was still blocked ,another ticket was logged and still went back to the store after 3 days and it was not resolved.im angry that my life is on hold because of your incompetence.i complained on facebook and was informed to go back to the store because the ticket is resolved .i wasted my petrol for the millionth time now doing back and forth.The store advised that they also dont kNOW..IM ANGRY BECAUSE THIS NUMBER IS ON CONTRACT AND IM EXPECTED TO PAY FOR THE SERVICES ..FIX THIS
