Getbucks *****ing my money

I made an incorrect payment to Getbucks. The payment was meant for Bid or Buy. After discovering me error I phone getbucks the next day to ask them to transfer my money back. After bank statement and proof of payment was sent to them, a guy called Hennie responded via email that I have to 12 to 48 hours for the funds to reflect in their bank then my request will be reviewed, meaning that my request can be declined or approved, im not making a loan so I cannot be declined to get back my OWN money, yes I know there will be a banking charge for them to transfer the money back and im more than willing to pay that, however, it can not take 12 to 48 hours to reflect on their side, it was an immediate payment made, the funds was available in their account immediately. Hennie never responded back to me after I begged to only be kept updated. This is not good service from this company. Im working in the banking industry so I know the ins and outs about transfers, it can be recalled by me via their bank, but I took the option to sort it out with the company directly, because incorrect transfers can cause a hold on the receivers account until the money is returned. I do not want to cause danger to their business but this is my money and I want it back ASAP.
