MTN - new system is a bust!

I have had a contract with MTN from time immemorial with monthly debits to my Credit Card - a few hiccups here and there but general eventually sorted - but I mean eventually!!! My latest taste of this iconically inept, ill-prepared, non-customer friendly telecom group is once again a frustration!! It was time to upgrade, so I used their online upgrade system so I did not have to frequent a physical shop - Covid and all that! Everything worked 100% ( thought to myself Covid has done some good here - they must have upgraded their systems - don't laugh!) The new phone duly arrived, I switched over & all good. UNTIL - the first payment for the new contract fell due - Standard Bank rejected the debit to my Credit Card alerting me to a possible ********** transaction. I queried with both the bank and MTN - nobody could help. I duly went to my MTN shop & paid the now overdue amount together with an admin charge via Credit Card for the rejected Debit Order and then asked them to double check that the correct Credit Card details were on the system - and for good measure we checked the email address as well. They confirmed all well and good. Great everything back on track……but wait there is MORE! A few days later I received an SMS from MTN advising that the email with my Invoice was 'undeliverable'. Ugh…. I managed to download the invoice from the App - so left it at that - hoping that the next month it will be OK. Yesterday I received a new Credit Card and off to the MTN shop I go to get the new Credit Card details uploaded. LO & BEHOLD - their 'NEW' system does not allow for Credit Card payments? The lady that was trying to help was actually flabbergasted and until then unaware or this new turn of events. I mean - come again??? Their front line staff were not even aware of this dramatic turn of events! Who in their right mind does not allow payment by Credit Card?? But I CAN pay physically in the shop with a Credit Card. What imbeciles at MTN have decided that they cannot use Credit Cards for Debit Order payments? MY guess? The idiots that programmed the 'New System' actually forgot to load a Credit Card payment option……….

For a company the magnitude of MTN - to have things like this occurring is mind boggling to me
