Good Afternoon

I've been having this problem since for about three months now and its only getting worse. There is a gas smell that comes and goes but is getting stronger and fills my garage I've changed both air filters and gas cap but the problem still continues. I believe my car may be apart of the 2010 - 2012 jaguar XF recall as I am having the same issues. I have called previously to ask about said situation and was told my cars vin isn't under the recall. Is there anything that you guys may be able to do for I am very concerned about my health that this issue are causing. Thank you for your time and have a good day.
