No recommendation

I was interested in a car from Global Motors which i then paid a deposit and then was told i had to pay an extra amount (more than 50%) to enable them to bring the car from the auction warehouse...they told me i can view it at their offices and then came with the story it will delivered to my address in nigel where i no longer reside at present...i cancelled the deal yesterday and the salesman promised for a refund today.. i cancelled because i need to see the car and test drive it..and then decided to keep my old car.. now they refuse to refund me because its not a valid reason...i don't recommend them to anyone.
