Delaying tactics with Deposit refund

I made a deposit payment using my credit card at the Silverlakes branch in April 2023 when I was interested in purchasing a car, unfortunately the sale fell through. I realised this year in in January that my account still has my deposit. I attempted to do the online payment and I was informed that since I made a credit card payment I need to do it with the branch. I requested that the branch send me the necessary forms I need to complete, that never happened. I called the central line and they gave me a contact at the branch I need to reach out to, when I called the person they told me they can't help me be cause they were not the agent who assisted last year and sent me back to the central line. I called the central line again and requested that the branch reach out to me on email with forms and what is required. Someone tried to reach out and they could and I called back again and the excuse I got was that they tried to contact me. I asked them why are they not sending the forms for me to complete and send back. I have since been in a loop between the central customer care line and their promises to get someone from the branch to attend to me. Still today nothing has happened. Can someone send the form to complete. Unfortunately I'm not around Silverlakes to physically go the myself. I intend to do so should I return before the matter is closed. I'm still looking for a car and I don't think I choose them
