After using the car, they automatically charged my credit card for toll fees but did not provide any receipt.

Car pickup was fine

Thrifty had forgotten to include the additional child seat as per my order and I had to personally drive to another location after picking up the car without my family to collect, fix the child seat myself and head back to pick up the family. The certified child seat installers were running late to work and I couldn’t wait another half an hour for them. Whole process took me an hour plus and disrupted my travel journey for the day. Also, upon returning the vehicle at the airport before departing Sydney, I had returned before 9am but they registered it as 11am instead with additional day charge. Still in dispute with them.
