Woolworths Financial services have gone to the dogs!!!

I have been struggling to get a refund payed to me on my store account since May 2021. I was in arrears with this account due to covid 19 salary cut, and the subsequent financial challenges that follow. When i was by the means to pay, i square up my account but by mistake over paid it by R2974.00 to VVM attorneys who, were appointed by Woolworths financial services as a collection agency. I have over the past months since May 2021 tried in vane to recovery my money but with no joy. I have an email thread of my communication with both, VVM attorneys and Woolworths Financial service as long as my arms but no one takes ownership of my plight. What to do now is the big question im asking??
