Worst Experience

I have had the worst experience with this company. I hired a car end of May and I have been waiting for my refund since April until now I have not received anything. I have sent numerous emails to them, they rep**** and said its being processed and that was 2 month ago. I sent 2 emails recently, they are now not responding at all. I do not know what to do anymore. I hope someone from the company reads.
