Never Hertz

I rented a car from 7 to 13 May 2018 at Hertz Port Elizabeth. The car was returned on the 13th without damage and refuelled. On the 17th I phoned Hertz PE to find out about the release of my deposit and the lady said it will take 7 to 21 working days to be released and I have to contact my bank. When speaking to a bank official she said Hertz must order the release. I again phoned Hertz on the 22nd and spoke to Charlise Jantjies and she said she will e-mail an authorisation to expedite the release of my deposit of R 25 150.00, which she did. I phoned her again this morning and said that I am going to share my experience on hellopeter because if they opt for 21 working days it means my money will only be available on 11th of June? Totally unacceptable!!! Never again!
