We specifically informed the staff at the counter that we did not want any additional insurance and the pick-up agreement stated a payment of $0 at the store. However, they added extra insurance without asking us and only asked for an electronic signature for confirmation. We thought it was for the deposit. When we returned the car, we found out an additional $150 insurance charge was deducted. It's very difficult to resolve such disputes in a foreign country, especially with language barriers. The staff only provided us with a complaint phone number and we had to complain ourselves. Changing our return date for this amount wasn't feasible, so we hope the rental car company can assist with this issue.
