MTN The Glen Mall (Johannesburg South)

MTN at The Glen Mall (Johannesburg South) is such a disappointment. My partner went to buy a phone (contract) on the 11th of May then the phone was misfunctioning so we returned it on the 15th of May 2024! They booked it in for OOB repairs and this took over a week. And they never keep us updated unless we call or physically go to the shop. They told us the have checked the phone but nothing is wrong with it they needed to update it. There's always some reason why the phone has still not been returned. It's been THREE (3) weeks now and we want to cancel the contract because how do you now debit the phone when we don't have it. This morning we had to AGAIN contact MTN and they respond after an hour say "we must fetch the new phone". HOW IS THIS POSSIBLE???? Terrible Terrible Terrible service
