Frustrated and angry client

I hired a car +/-month ago 21November 2019 till the 25th November 2019,which was return in a good condition as requested. I was told my deposit was going to be deposited in my account 3-5 working days. No money has yet been payed back from the company. Ive been phoning after them continuesly with different answers. It's been weeks and the company is giving me the run around. Very unprofessional but yet my money was good enough to take but not enough to pay it back.
