Nedbank personal loan department does not know how the **** to allocate payment

I am so upset as I type this review. Nedbank has failed me yet again. Although I bank with capitec I have a personal loan with them. I was double debited and now all of a sudden they didn't receive payment. I'm annoyed because not once have I defaulted on payment, not even with the covide 19 pandemic. I received a call from avert rude consultant requesting payment. Today I sent my statement showing payment was done to ***. Still no response, not a call absolutely nothing. I wish someone can tell me what the **** is going on. Is the capitec or nedbank where the **** is the more than 3k amount because its clear as hell that it is not in my account. I need to be contacted asap. Stop sending me from pillar to ****en post and do your job.
