CARtime drops the ball

On 24 June I contacted Cartime Hillcrest and ask if they fix aircons on vehicles, after some delay I was told yes, and to bring the car in. They changed a pollen filter and re gassed the vehicle and called me to say all is good, and to collect the vehicle. I was charged R 1919.58. I climbed into my car and found that nothing had changed, aircon was not working at all. I contacted them and was told that they were trying to "make a plan". Since then I have called everyday, just to get excuses. Not once have they called me. No Refund???> I am short R 1919,58 and still have a non functional airconditioner. Its now 8 July.
