Bad Service Operating like ****

I rented a Car with reservation ***.the invoice was Xlosed on Monday the 8th January 2024. Intentionally europcar has been holdin back to my Deposit. I called them Friday the 13th they Promised that they Paid the Money in my account on the day up to today there is no deposit refund in my account. They act Like ****mers because tney have tyre and Windscreen cover and still when something happens to tyre or windscreen deposit is not released. So why create an insurance when u stil have issues. This company need to improve how they treat People
