MFC debit order ****

I've been a client with different cars and accounts with MFC since 2013 not once have I missed a payment or received a demand for payment. My first debit order was supposed to go off the 25th March 2020, my funds were available I waited and nothing was debited I was so concerned I checked my account to see if the debit order bounced but not debit order attempt was made. I waited until the 1st of April thinking maybe they had my debit order date incorrect still no debit. 15days later and heading into the next Month's debit no call or sms from anyone to say sorry there was an issue with our system. I thought maybe this is a covid 19 assistance that MFC never debited my account or called me. On Thurs I was called which was 18days later saying my account is now in demand. I told the agent fine debit my account but I'm not happy I'm furious cause MFCis putting my name down the drain with their faults. No one debited my account, then I got an email of demand the same day and telling me the client to call at this point I was furious, I mean my first debit order, I call the call center wasted R200 airtime waiting to speak to someone for an agent to tell me my account was handed over. I called the department and the lady working on my account was cheeky and put the phone in my face, called again she tells me I must just go to nedbank and my bank for a Debi check which I've never done before being a client with MFC what the hell, I told her why is this my problem now, she just said make the payment and I mustn't raise my voice she put the phone done again making this my problem I tried calling the direct number back and she kept ignoring my calls. I'm actually ****ed. No where does it say if a bank doesn't debit on the promised date things becomes ur problem. The client must run around for a banks fault. Is this a Covid **** that banks agreed to surprise clients with interest and double debits. She cud read my account number even.
