Auto max please do something about these guys.

My brother bought a car from Alex, he brought it home on Wednesday 20th of January 2016 and that same Friday the car stopped working at a freeway he was assisted by another driver, so he called them and they said he must bring the car back( the immobile car) he told them he cant as it is not moving and they insisted that the only way to help was for him to bring it back. the morning of the 10th February 2016 he tried to take the car back but it died on the freeway again and he had to call a tow truck to pick him up and he took the car back to them and since then they have been giving him a run around about the car. it is still not back ( 25/02/2016) so wants again a client is paying for a car he doesn't have from this Dealership and when i called them they swore at me and put the phone down while i was still listening to them go on about me not having a brain. this all because i told them that my brother as a Customer has a right to get a refund from them since this deal is not working out. The car fault is an engine fault and was not in anyway caused by my brother.<br>
