Very dissapointing service. I want my deposit back.

This is the email i sent and have since not gotten feedback but slapped with an invoice to pay.

Concerns: 1. When i called your callcentre for a quotation to hire a vehicle i specifically requested a VW polo and confirmed pick up on the 12/01/2020 but was surprised and dissapointed to be informed of the non availability of the polo and was offered a car in the same group which happened to the Renault cleo in question. Note the vehicle came with a full tank and 400km free over the 2day hire period, which i returned on the 14th Jan 2020 and only filled petrol then. Meaning i drove the vehicle with the fuel it came with and not used it with the fuel i topped up with. Why then would i be billed for damages of fuel that came with the car? 2. I exchanged the vehicle in perfect condition on the 14-01-2020, for a polo which is due to return tommorow 28-01-2020. The person who was helping asked why i wanted to change and i did inform them that it was not what i wanted in the first place, and the brakes were a bit noisy. 3. What proof do i have that the vehicle was filled with 95fuel and not a mix of both 95&93 from the date of hire? 4. If there are specific instructions to be followed for fuel in your vehicles, how is this communicated to your clients beforehand? 5. I called the call centre this morning 27-01-2019 to inquire about availability and a quote to hire a bakkie as i intended to again use your services but was told to hold so i can be transfered to OR tambo branch and after hanging on the phone for over 10min with no answer i hung up. very dissapointing. 5. This is my first experience with your organisation and has not been a pleasant one at all.

Greetings

I acknowledge receipt of your email. As per my conversation with thabo Vilakazi earlier today i do not accept responsibility of the incident and will have to pay a visit to the petrol station at OR tambo skytop to retrieve a receipt of the fuel used to fill up that car before it was returned to you and therefore request that you give me a few days to do that.

In the meantime i would appreciate if you would furnish me with a report of the inspection carried out by your organisation before i took the car proving that a thorough check on all items was done, by who and when.

kind regards.
