Credit apparently returned but not reflecting

I was under debt review, and paid up my accounts at the end of June 2015. My personal loan had a credit that was supposed to be refunded to me.<br> <br> According to one Nsizwa, the money was paid into my checque account on 28/07/2015. I have never had a cheque account with Nedbank (my current one is with FNB) and my saving account I had with Nedbank hasn't been active since 2011.<br> <br> Despite several requests, Nsizwa has not yet provided me with a proof of payment. I only have his email, not his contact number.<br> <br> The reason I left Nedbank in the first place, is the poor, useless service I receive. Nothing that has happened recently has changed my view of the terrible customer service they provide.<br> <br> Please ensure that this matter is rectified as soon as possible, and that I will get my money back.
