Bad service received.

Good day, My experience started off to be great at Eurpocar until they 1st gave me a vehicle that was making funny sounds as if the vehicle was just a about to break down. I went back and received a replacement vehicle which was fine no issues. My vehicle was fixed on the 20 Feb and ready for collection and this where my problem started. I accidentally forgot my daughters brand new shoes in the vehicle and when I phoned, I was politely told it is gone and if I'm sure the shoes were in the car. I kept on explaining that I forgot it in the back seat on the vehicle. Europcar billed my so incorrectly for tolls gate I never used. It is a back and front story one agent say this other one that. so unprofessional. received my invoice today after numerous of calls made to them. what bad service I received?
