Universal located in Missasauga is Predatory

I went to visit Toronto for a week during Christmas a few months ago. I had planned ahead very well and purchased my car rental from Universal Rent a Car through carrentals.com. I would not recommend using carrentals.com either. I was quoted a very good price online, something like 11 dollars per day and I purchased insurance already online through carrentals.com also. The website really made it seem that universal was located at the airport, but I couldn't find it and to my surprise it was located about 20 or more minutes away in Missasauga at the Stage West Hotel. I had to wait almost 45 minutes outside in the cold snow for the driver to pick me up and the van he was using looked a bit scary. It did not have any logo on it and I am a woman alone. The driver was inappropiate telling me of his excapades with girls and bragging bout how many women come on to him. Once we arrived at this dinky hotel the guy at the counter was abrasive and talking super fast and didnt even make eye contact and he was screaming at other customers on the phone. I thought that I had already paid for everything possible but they told me that they needed to hold 500 dollars on my credit card which I gave them but i didt really have that money to let them hold on to. Then they said I needed to pay these crazy fees for insurance which came out to close to 200 dollars for the week. They told me that I had only paid for comprehensive not liability online. I was peeved at this point but I understood. then they told me that I had booked the rental for 12:00 noon but I came at 2:00. They charged me some crazy fees for being 2 hours late. I didnt book the car for 12. They told me that the car I rented was gone so I need to pay for a larger one also. They ran and re-ran my debit card so many times that my bank locked it becasue I am in a foreign country and they rudely told me that I was out of money, which I was not. This whole ordeal was costing me almost 1000 to rent a car for 5 stinkin days. I was basically stranded and was afraid of what to do Christmas week so I went along with it and did not complain but I was giving them evil looks. Finally when he goes to give me my huge full size car which I really didnt want because I'm not familiar with driving in snow it had beer cans in it, snow in it and he pops the hood and starts mantaining it right there in front of me. It has half a tank of gas and he tells me to just keep my eye on it and return it with that same exact amount and I wont get charged. I felt like crying cause I felt used. Then when  get in the car I discover that the driver has left to pick up more victims from the airport with all my luggage still in his van. I waited well over 40 minutes for my stuff to return and in that time I heard the manager yelling at at least 3 more customers. He actually yelled at them mostly bout charges. I was afraid at getting even more victimized so I decided to cancel as soon as my luggage returned and after alot of rudeness I was able to cancel but had to pay  about 175 CAN. The guy started yelling at the driver about my case and they mostly ignored me and I was left to fend for myself very far from downtown Toronto where I was staying. The cab ride was 65 CAN, and with my credit card having so many transactions I could not spend anymore money that day. Stay far away from these guys. While I was at the Stage West hotel trying to make arrangments for my ride I was told that my story is very common with those guys. I delt with 2 younger Indian guys and the business is family and friend owned so no complaint matters.
