MTN BAD SERVICE

My credit card expired the end of January 2022, so my debit order did not go through for the payment of my monthly account. On 28 Feb, 31 March, 3 May and again today 31 May I received a sms, saying that MTN has not received payment. On these mentioned dates I went into a MTN store to make a credit card payment and request them to update my banking details because I received my new credit card. After FOUR visits, including today, the problem IS STILL NOT RESOLVED !!!!!!!!!

So I am really FED UP with MTN's lack of service. Whether the problem is *********** personnel at Savannah Mall and Mall of the North in Polokwane, or a system fault from MTN, I do not know. But to visit a store FOUR times ta ask them to update my new banking details and it is STILL NOT DONE, is absolutely ridiculous. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! So, does MTN expect me to go to a store a FIFTH time ??????????????
