American Residential Warranty Will not respond to cash out offer becuae tech didn't provide serial number but it is available Boca Raton Florida

Contacted ARW about my a/c not working, they sent out tech who said compressor was bad and it is cheaper to replace the unit than to repair. ARW decided it would be cheaper for them to offer me a $700 cash out since unit was about 12 years olds. Don't know how they came up with that since the house is only 9 years old. I've spent the next few days trying to contact them about th this error and give them the serial number so they can verify the age of the unit. According to the seial number it was built in 9/2006. Now awaiting call back, which I am sure will never call back. The have no problem taking my money every month like clockwork.
