Reversed payment no explanation

On the 25th January 2016 I made a payment towards my partner's loan with Capfin of R500. His account was handed over to Ver-tex Solutions.<br> <br> When he asked for a statement yesterday we noticed that the payment made on the 25th January 2016 on my bank statement reflects on their statement on the 28th January but was also reversed on the same day. I have looked at my bank statement there is no evidence of me reversing the payment made.<br> <br> We get told that they can only give feedback in 10 days, but that is not good enough. How do they not know what happened. Can they please credit the account accordingly with the payment made in January and to adjust the interest accumulated since then accordingly. I have sent the loan statement and my bank account statement to [Email Removed]
