FIRST CAR RENTAL IS TO BE AVOIDED

I have had a query for a few weeks now as this company is *****ing from me - they are charging me for the petrol used to take back a car that had 4 tyres that kept losing pressure and the petrol used to bring me another car. They have said as a goodwill gesture they will not charge me for the kilometres they used! But they are still charging me for the R300 I put in the first car when it was collected from me (I gave back a car with a full tank as if I had handed it back at the airport), so in fact am being charged for the petrol THEY USED to take the car back to the airport BECAUSE IT HAD FAULTY TYRES! I also received the first car with a tank that was not full. I do not expect them to pay for the petrol to fill the second car when I returned it but I put in R300 when they brought it to me and they should have given me a car with a full tank. This R300 should be credited to my account as well. This was petrol THEY USED to bring me a replacement car. They stated that the tyre pressure was affected by 2 Mags that were damaged during the rental - NOT DURING MY RENTAL! The damages were noted on their forms by the inspector in the parking lot when I took possession of the vehicle. These damages were not marked on the form by the inspector when the last renter returned the vehicle. So why am I being charged because they gave me a vehicle that had tyres that kept losing pressure which to me made them unsafe and the company needed to rectify the matter by giving me a safe vehicle. NO ONE WILL GIVE ME THE CEO's EMAIL ADDRESS so I can forward the complaint with the list of events to him. They hide behind their Customer Services Dept. Yesterday, someone was supposed to phone me and I am still waiting - they think their gesture of Goodwill is enough!
