Hertz Complaints Turnaround time is pathetic

Hertz has a very poor turnaround time regarding client complaints. I have sent my first email on 13 September 2018 complaining about the invoice that they issued to me after my rental with them. I have sent numerous follow-up emails but have been thrown from pillar to post. I am not happy about this, anything involving client overcharge has to be attended swiftly. The worst on that invoice is that I returned the car with certain kms but when I was billed I was charged for fuel for km that I never drove. This means that the car attendants there use the cars that are dropped by clients for their personal travel and only afterwards they log in the vehicles as returned at a later stage. the invoice number for anyone that wants to investigate within Hertz is ********** 7−1 . On top of being charged for extra kms, I was also charged for an extra day but I returned the car on time.

I have been waiting for this to be resolved but to no avail. It is ridiculous!!! What is more irritating is that this is not the first time. The other time I returned a car with full tank, but guess what, the invoice came back saying the car was empty. After numerous and another long waiting time, I managed to get the fuel money returned back to me.
