Disgusting service from MTN

I'm disappointed by the service received from MTN. My name is Vuyelwa Lothe and I have used the mtn number *** before my kids where even born. In October 2019 I couldn't use my number because suddenly it belongs to someone. I phoned and spoke to a lot of consultant to date my issue hasn't been resolved. I am forced to use a vodacom number***)fter all the years I'm disgusted by their service.
