MTN NON-EXSTING CUSTOMER CARE

MTN is making my life a living hell now yhoo! I am about to move my business elsewhere because of their non-existing customer care, yet they call them Bozza. I have two data contracts and one is due for an upgrade which I did online on the 25 April 2022 until this day I have no proper response from both the customer service line and the store which tell me to call the customer service. Such disappointing customer service MTN!!!!
