Cheap Car Rentals in North Center, Chicago from C$ 82

My original prepaid reservation was unable to be fulfilled due to low inventory. The counter agent at that location told me to check back the day of my departure to see if any cars had come in. I tried calling three times and no answer. This forced me to travel to another location to secure a rental. First I was told I need to call the corporate support center to have my reservation pick up location changed. The representative quoted me a price four times as high as my original pre paid reservation. I asked to speak to the supervisor and was put on hold for nearly ten minutes before the support center ended the call without solving my issue. The counter agent at the new location was helpful and suggested I create a new reservation to ensure I get a car before they run out. That rental charge was still more than double what my original prepaid reservation was. I am still waiting for a full refund for my original reservation and I believe Hertz should honor my original paid fee and adjust the charges. Also, I received a fraud alert from my bank saying Hertz was trying to process a $100 charge but I do not know what for because I still have not received a final receipt which I was told would be emailed to me when I returned the car.

Waited 2 hours because no cars were available also the car was dirty inside
