Hertz car rental review & Complaint

I rented a car via Gage car rental but they told me I'd get the car delivered from Hertz. I had the car for about 9 /10 days , I was told it had to be returned with a Full tank and in good condition which I did I returned the car on the 4th of April. The next day I got an email and I was made aware of the deductions (E-tolls and fuel) and everything was smooth until I started following up on my Deposit refund. I have since sent Emails requesting my Deposit, my emails were ignored, calls go unanswered (I had a terrible experience with their customer service from the beginning. I would call and get no response at all , send Emails only to have them reply days later).

Anyway, since I was being ignored, I then sent another Email and I escalated the matter by involving Gage. They (Hertz) then told me the refund would be processed on the 21st, I followed up again after I did not receive anything and told the Gage Consultant that I didn't think they even processed this payment, I was then told it would take 2- 3 days to clear. Today is the 27th of April , I still have not received my Deposit refund from Hertz, No proof of payment nada. Very terrible customer service!
