Loyal Client for years receiving the worse service

Vodacom’s service is so bad and frustrating. I have been gracious and nice from June with the call centre and vodacom official. It is just to frustrating. Phone contract was suppose to be up and running since June 2020, but still not sorted out. The call centre is just useless I want to sort out the problem and when I call I can’t get hold of the person to sort the contract problems out and no one is taking accountability. Nothing is getting done to help me as the customer. It has been since June. I have been a loyal customer of Vodacom for all my life and it is just shocking for me that they don’t sort out the problem as I am a loyal client. The fact of treating me the client so wrong and not listening and sorting out the situation is just shocking for me and it is so frustrating.
