I have a 2008 Nissan Altima in good condition, no ...

I have a 2008 Nissan Altima in good condition, no car accidents, and I keep it maintained. Towards the end of May, my car "stalled" when I was driving.. My dad (knows cars well) thought it was the alternator but Nissan said it was not the alternator and that I needed a new battery ($200+ later I got a new battery). The day after getting my car back it stalled again... they had my car for 4 days and finally said it was the alternator and that it was going out "intermittently." I am grateful they kept the car and figured out the issue, but 4 days is a long time to be without a car and ($600+ later). I get my car back, AC does not work.. I then take it back to Nissan for the 3rd time... oh they forgot to reconnect something... A few days later the dust cover under the car came off and was dragging on the road (I had paid them to fix that when I got the new battery) 4th time I go up and they fix the dust cover. The next day after getting the dust cover fixed for the 2nd time, it comes off again. I drive up to Nissan for the 5th time.. the service center was closed. The cover was dragging under the car, and I was not able to take it off myself, but instead of offering to help me or find someone who would, the salesman who approached me was more concerned about being liable if he took the dust cover off. Let me add that I am a female college student, so I do not know much about cars, but I know about human decency, and he could have at least offered some sort of advice instead of rambling about being liable.. obviously I could not continue to drive like that but luckily another sales associate was kind of enough to help me get the dust cover off just so I could drive safely for the day. So the next week my AC stops working again, I take it back to Nissan for the 6th time.. oh this time I need a new Air Compressor!! The offered to put me in a rental for a few days, and the rental manager was extremely helpful and kind. They had my car for a few days and $1100 later I have a new air compressor. The day after getting my car back the AC stopped working again. I drove up to the service center for the 7th time at 2:20 on Saturday.. no technicians were there, they already went home.. their hours say they are open until 4. I was approached by Jessica, a service advisor, she said no one was there that could look at my car and I would need to bring my car back Monday. I explained my situation to her and she understood my frustration of paying over $2000 for this car in less than a month and its still not fixed. Jessica was extremely kind and apologetic. She put me in a rental quickly, and said they would have my car looked at on Monday. So to this point I paid for a battery I did not need and possibly an AC compressor.. I await the call on Monday to see what is next...

Sidenote: During my 7 trips to Nissan in a month, my service advisor was Mike Little. My first encounter with Mike was after the replaced the alternator. I went to pay for my car at the cashier and she directed me to Mike to get my car pulled around front. He looked at me and said "who are you, what do you want?" I was taken aback, but assumed he was busy so I said I was picking up my Altima. He handed me my keys and told me just to go get my car from the back... it was raining.. and there were many, many cars in the parking lot of the service center.. I just paid over $800 and then was handed my keys and told to hunt for it in the back parking lot. Thankful I have an alert button on my keys that I could use to find my car amongst the huge lot. Unfortunately, every time I have dealt with Mike, he has been demeaning and condescending. VERY DISAPPOINTED and wondering if it is because I am a female in my 20's and what could I possibly know about cars or anything else for that matter?
