Non Refund on deposit

I wanted to hire a car from eezy car hire. I contacted Paul Rood and he said that they will only have the car available on the 12 of dec 2015....but in order to keep the car for me I had to make a deposit of R1000 and on delivery I must pay 3550 which I aggreed. On the 12th of dec Paul phoned me saying that they havent received the car back as yet and he will let me know when they do. On the 13th of dec they still havent received the car and I asked Paul yo pay my deposit back cause clearly I'm not going to get the car and I had compassion for him being in a situation like that not getting your vehicle back....turns out the car was in a accident ect......I phoned after 4days for my deposit and he said it was payed in and he will send me proof of payment, I sent several text messages and he said he will pay the money in....but no money or proof of payment on their apparent payment.....on 21 dec I phoned again and he said he will see to it.....I have been phoning for 2days with no answer or any reply on my messages. They keep a deposit on a car which I did not even received.... I desperately need my deposit back
