Bad service and making a profit on unearned interest

Terrible service and waiting for my deposit and ins cover. See my email to Firefly. After waiting for a response from your telephone number for over 9 minutes, I am now emailing for some assistance. I booked a car from Cape Town airport from 27.11.2019 to 30.11.2019. I have, to date not recieved my deposit of R1650.00 back. Had I known that the block on this amount would be withheld for so long, I can assure you, I would not have used your services as none of this has happened before. I usually have my deposit back the same day I drop off the car with other rental companies . This is the first time I have used Hertz and I am terribly disappointed. When booking the rental, I was led to an insurance page which charged R1216.00. On arrival at Hertz Cape town I was informed that I should cancel this and take your insurance. I was then promptly handed a phone with an Irish accent on the other end that assured me I would get my R1216.00 returned as your consultant had told them I was cancelling their cover and taking yours. I have no number to call this international connection and I have not recieved this money back either. I also do not think it is my place to run up additional costs getting my money back from an international company. My attempt to contact rentalcover.com is useless as I cannot see that the booking was cancelked. It states that it is confirmed. Your help desk assistant at Cape town Hertz has caused me endless worry by being so flippant in getting your cover and cancelling the original booked cover. The 4 days I spent I Cape Town have been marred and spoiled by Herz and their ability to NOT inform the traveller of the unexpected costs that are not refunded timeously and the loss of interest I am getting. Please can I have a call from one of your people in your accounts department or customer care to discuss this further as I am nor prepared to sit on my phone all day waiting for a response from your call centre.
