Engine Exhaust System Problems of Mercury Milan

I brought my 2008 Mercury Milan premier (purchased 7-30-10) as a cpo vehicle, 6,900 miles, to metropolitan Lincoln Mercury, garden city, mi (734-458-1961). I reported the driver's seat mount was completely rusted out and needed to be fixed (they refused, saying it is normal), there is excessive traveling distance when braking (they said the brakes were "fine"), there is excessive exhaust noise (a known problem that they said they don't know when the fix is coming), and the transmission doesn't shift properly (stays in one gear too long/also a known problem). For known problems, either I have to pay for it (the transmission) or they don't know and don't care about the other known problem (a resonator for the exhaust system to reduce excessive noise). I have never heard of seat brackets rusting out being normal. I feel if left unchecked, it may become a safety issue. Despite the fact I bought an extended warranty, it appears they want to come as close to $100 as possible (my deductible), fix one item, and then get me to come back again, so they can collect my $100 deductible again for a problem they did not address the first time I complained about it. They said the rust is normal although I have never in all my life had a car that rusted out in that area and it is absolutely not normal, a hazard and must be fixed. Obviously, they have chosen to deal with issues that are only simple, where they can make the most money/don't have to dole out any, and avoid ones where the obvious solution is too costly, may cost them some money, or are too complicated.
