Double debit due to MTN inability to process timeous payments! Customer (a Pensioner) prejudiced!

Is there a minus review? If not why not? Mind you, why would they care?!!!

MTN processed my long running monthly Debit Order for April subscription late, in May 2020 - on 7th May 2020 (usually debit order is processed on the 1st of the month - this covers the payment for the previous month debited to my MTN bill on 11th every month) Presumably because of the lock down, their account records were not updated timeously resulting in the amount for April showing as outstanding on my May statement (even though it has been processed through my bank account) and reflecting the amount owing as being the April & May subs. I assumed that this would be corrected/updated before the debit order for my May subscription would be processed in June - WRONG!!!!! I mean is it unreasonable to assume the Accounts Department would be working as an ESSENTIAL SERVICE???

THEY HAVE NOW DEBITED ME FOR APRIL AGAIN TOGETHER WITH THE SUBSCRIPTION FOR MAY. No answer to their "Customer Care" centre - and from previous experience not much good in trying to queue to see a Customer Service "Champion" in store - as they have no control over the "Account" section.

Talk about ****ty service!!!!!!!!! As a pensioner I do not have reserves to cover MTN's poor service! How do I get my money back? If I ask my bank to reverse the debit order, MTN will just block my service………..
