POOR POOR POOR!!!!!

I bought a recliner set early in the year on credit, my last payment was November 2020 where the debit order was R1 126.60 each month ,it changed for the last month and I only had R750 left to pay. They sent me an sms to confirm they will be deducting R750 from my account on the 1st and I received a statement with the same amount as well, but nothing happenend I phoned the help line and the guy explained to me that its in transit and the febit order will be going off as long as the funds are in my account wich it was. I then received a payment from someone and 2 min later the debit order went off R1 126.60 I immediately phoned help line where I had to hold on for 25 Min and was transfered to like 10 different people had to explain what happened to each of them before I got to the financial lady. She then told me that its the system and that I would have to wait 3 days for the money to reflect in their account and after its been cleared it will take 14 working days for my money to be refunfed,and I must go to the Rochester store and submit my ID and bank statement for them to even start with the refunding process. I went to the bank and try to reverse the payment but as they do a debi check debit order it can not be reversed even with the help of the bank. I also requested a letter saying that the credit is paid in full and the debit order is stopped because what if it happens again and her reply was I can only get a letter when the money reflects and then I can submit it back to them to request the debit order to be stopped. I am to this date still waiting for MY money to be refunded. I will NEVER EVER buy something from Rochester again. The service is so poor!!
