Refund Deposit not paid and no feedback

I paid a deposit of R5000 and I didnt get the car I wanted, I requested for my deposit back and I was sent a refund form to complete and send back with proof of banking and Proof of payment, I did complete and sent the form and required documents on the 18th January, I then did a follow up twice with no luck till today, I made a phone call today which were dropped twice until they took my number for a callback which never happened. After reading some of the reviews here I realize I will not get my money within the 7 days on their T's n C's. I never had this issue with SMD before.
