Quick online booking,zero communication between third party online and front desk staff

Upon arrival i was very miss lead on the options i had previously purchased.at the time of of arrival i was told of no insurance,a small 3 cyl car and no discount for 1 day early return.i was charged a extra 300$ for insurance when clearly i had purchased it already online beforehand.myself being calm and asking what was the excuse for the extra charges,the front counter staff had zero explanation for extra charges and wasnt provided with honest straight answers on my paper work i had provided,they were just quick to get my credit card funds.being accomadating to my requests,they had “granted” me a complementary upgrade vehicle which was the exact one i had payed for online anyway. For the next 2 months i have once again booked my rental vehicle through you guys again hoping to see what future changes can be applied Jesse gow
