Review FRAUD: NON ACKNOWLEDGEMENT OF PAYMENT

I made a repayment of N28,841 via the app for my loan repayment on 15th June, 2021 but it unfortunately failed so I did a bank transfer same day and took another loan some days later. Unknown to me, the failed app payment actually impacted and my bank account was debited. I took this up with my bank and they confirmed, after days of investigation, that the app payment was actually successful. So I took this up with the okash agent who promised me that a reversal will be done in 3 days but rather than get a reversal I keep getting irritating calls and chats from different agents on a daily basis asking me to pay my loan when in actual fact I still have funds with them which they are yet to acknowledge. The organization is so unstructured as I have to send proof of payment for both the bank transfer and the app repayment repayment to 4 different agents, each with a promise to sort it out but never really doing anything nor documented it. The painful part is that my loan balance keeps growing and their 'uncultured and saucy agents' keep disturbing me. This fraud has to stop.
