Hidden cost and poor customer service

Hidden cost on the car rental company you do business with. Rentalcars.com does mot disclose all the fees when renting a car. Please rectify this, its unfair to the customer. I have lost more than 1000 now cos i did know that the security deposit is 13000. If i knew i was not going to book the car. Even contacted hippo today yesterday with no help, then later i contacted rentalcars.com and had a chat with John who could not help me with the amount of the fees i will be paying a s security deposit, if he helped me then i would have cancelled the booking in time and receive all my money. Then i chatted to someone i cant recall the name, but still no help. Then finally sidney from rentalcars.com helped me when it was convinient for them to take more than half of my money. Been seeking help from the 27 december 8:41 in the morning ,if i got help in time regarding the security deposit i was gona cancel in time or if the security deposit was not hidden.

Please correct your mistakes and stop working with **** company,
