Complaint Review: Sixt Malpensa airport Milan Italy

I hired a car from Sixt at Verona airport. I was given the keys and told I'd find the car at the far end of the large covered parking shed. When I found my car  I walked around it and it seemed fine - although it was anthracite Grey and the lighting was not very good. As I stooped to get in I noticed some dents in the roof. When I looked more closely the roof and rear tailgate were covered in small dents. I reported this to the agent and she marked "hail damage" on the diagram of the car on the paperwork.

I returned the car to Sixt at Milan, Malpensa Airport. As I parked, the Sixt agent came to me and took the hire papers and started checking the car and fuel whilst I removed my belongings from the car. He finished his inspection and thrust the papers back to me and said "OK, sign here". I signed, without really looking as I thought all was "oK". At home the following day I found that he had drawn a small dot next to the wing mirror and written" Graffico" - the italian for "mark" on the form. It was done so you did not notice it at first glance. At no time did he indicate anythingwas wrong and he made no attempt to show me any damage. Sixt are now charging 80 Euros to my credit card. I have e.mailed them 6 times and received no useful responce other than "we'll contact you in a few days". Attempts to phone their customer services are unanswered, I spent 1 hour listening to an announcement that they would be with me in a minute.

This was a deliberate fraud. I do not believe there is any damage. I was stupid enough to sign, when the guy said "OK".

Sixt gave me a car covered in damage and did not warn me. Would I now be being charged for Hail damage, had I not spotted it and got it recorded?

This was my first time with Sixt- it will also be my last time.

Beware, they seem to be a very unethical company, with very poor control of their staff and absolutely no care about customer service.
