Very Bad Service

This is the fourth country I have done self-driving in abroad: Russia, New Zealand, the USA, and Canada. This time was the most frustrating, not because of spending more money due to language barriers, but because of the service attitude of the car rental company staff. In the other countries, even though I didn't understand the local language, the car rental company always made sure to clearly inform us about any additional charges. However, this lady had a very average attitude. When she saw we didn't understand English well, she didn't make an effort to communicate properly. When I asked if there were any extra charges, she didn't explain clearly and just said OK and had me sign. Only after signing and seeing an additional 200 CAD charge on my card did I realize what had happened. Communicating with her was difficult, and we initially thought it was a deposit. When returning the car, the inspector clarified with a simple explanation that we were charged over 200 CAD for insurance. Despite explicitly telling her I didn't want insurance, she still applied it. The problem isn't the money but the attitude toward service.
