Refund

I mistakenly overpaid Strauss Daly in access of R19 611 on the 17 December, I called to enquirer if payment has cleared & how soon can my refund be processed, they confirmed payment was received, however communication was unclear regarding my refund, instead was told the guy I dealt with from the beginning is not at work (Bradley), which made me wonder if Strauss Daly is a ONE MAN SHOW, how ever I gave them benefit of the doubt, now it's been 7 days & haven't heard anything. I believe Strauss Daly is acting on behalf of STD Bank, which I will be taking the matter up with my private banker there if I don't get immediate assistance on this platform, further more will escalate the matter to the ombudsman. Please process my refund ASAP.
