Pathetic Service

I had my MTN number blacklisted after losing my phone. On the 10 April 2021 I went to the MTN store at N1 City Mall, Goodwood to do a sim swap which costed me R150. Up until today my number has not changed instead the store gave me a number that belonged to someone else. I called Ebrahim (who assisted me at the MTN store) and asked him for contact details to escalate the issue and he said there's nothing I can do but wait for the issue to be resolved, after 4 days! The lack of urgency to have this resolved is frustrating as my life is practically on hold while they taking their own sweet time resolving the matter.
