Other Fuel System Tank Filling/charging problems of the 2011 Nissan Juke

I purchased a used 2011 Nissan Juke from a Nissan dealership. At first I had trouble filling up the tank. I brought it back to the dealer I purchased it from and they found a plastic piece from a plastic gas can stuck in the tank. From the moment I purchased the car, whenever I fill it with gas, my car, clothes, garage and first level of my home smells like gas. I looked on the internet and found there was a recall for this issue in 2012. I believe that whomever serviced the car for the 2012 recall did not do it properly. For the past week and a half I've been in contact with Nissan customer service who either disconnect me, give me incorrect information or don't return my phone calls when promised. I was told a supervisor would get back in touch with me in four to eight hours. They called me back three days later. I feel like my car is a death trap. I'm afraid to park it in my garage for fear that when I use my electric garage door opener, they're will be a spark and my entire condo will explode. I'm afraid to drive it for fear someone will toss a lit cigarette and the car will catch fire with me in it. I've had more migraines since I've purchased the car than I've had in 30 years. When I mentioned the problem to the Nissan dealer whom I bought the car from, I was told I needed a new gas tank cover. I've bought three of them with no improvement.
