No refund received

Hi MFC Auctions,I was interested in a car which when I firstly enquired i was told the car is available for purchase,soon as I had the funds ready for the transaction I was told the car going for an auction which I needed to deposit the amount to reserve the car. I deposited the amount but was was told it had declined as my payment was late so I was informed I needed to pay an extra amount which will total a 50% of the advertised car amount. I suggested that I will kot be able to pay the amount as I haven't seen the car which I have been promised a refund which I am still waiting for. Nobody is answering my calls and the sales consultant including the senior sales consultant are ignoring me especially Shane Micholsonwhonis the senior consultant
