No deposit refund received

I rented a car from the Europcar Port Elizabeth airport with date out on 13/01/2018 and return on 14/01/2018.

I have sent mails to Europcar to enquire as to when I will receive the refund of my deposit, up to date I havent heard a word and the customer care line merely said that I have been waiting an unusually long time since it exceeds the waiting time.

To date I have not heard or received a single call or email from them, I suspect they are super ***** and suspicious.

The rental agreement number is ********** 06. Hoping to get an answer soon or the company will be faced with legal proceedings.
