Poor Customer Service

REF: ***, I don't regret not renewing my 2 voice lines that expired a month ago , only last 2 to go and I'm done with MTN, their services continuously deteriorate. Guess what, for the above mentioned case opened in Jan/Feb 2022, only received sms notification today after a month that my query is been attended to, only now sending sms. When I called the customer care Agent ,as I was puzzled what's this reference for, the consultant said is the query you logged beginning Jan/Feb ....sorry MTN you are too late and the consultant was like sorry, the sms was sent on error.
