Refund

This is the 3rd review I'm posting. This matter is still not resolved

I had a loan with standard bank and it was handed over to vertex but they still continued debiting my account. On the 27 October 2021 both of them debited from my account and the loan was paid from the money that standard bank debited from my account. I've been to standard bank and I was told that they never received any money from vertex in October. I called vertex many times and they keep telling me that they are waiting for a response from standard bank. I wrote a review here on 31 December 2021, vertex called me to say they are looking into the matter. No feedback since then. Standard bank sent me an email requesting more information. My emails are not going through to them when I reply and I called the number attached to the email, it doesn't exist. Where is my money?
