Cannot get my refund processed

I opened an online account with We Buy Cars earlier in July 2022 and paid a R6000 deposit into the account. I was able to effect a refund once I determined that there were no vehicles that I was interested in purchasing.

I made a second deposit of R5000 in the hopes of finding a vehicle that I liked but again could not find anything. I am trying to effect a refund however the refund button on the website is not allowing me to do so. I did not make the deposit via credit card and the second deposit was made in July 2022.

The refund process was easy to effect the first time, however now I am quite concerned that I cannot effect the refund. Please may I be assisted with my refund.

Thank you.
