Quick question about an incident which happend today

Hi everyone,
I have a question for people who fly in CT, and NY often. Today I was
flying from Danbury (DXR) to Brookhaven (HWV). I flew out without incident.
Coming home I flew from Brookhaven direct to Calverton then to Bridgeport
then direct Danbury using a combination of my sectional chart and GPS as a
backup. The whole route was flown at 3,000 ft with the exception of takeoff
from Brookhaven and a decent about 8 miles to the south of Danbury. Upon
arrival ground control at Danbury gave me a phone number to contact NY
approach on. I called the number and was transferred to a controller who I
told my call sign the control accused me of flying through the Westchester
County Airports airspace at 2,800 ft. I was never within more then 20 Miles
of White Plains on my whole route. This is confirmed with my GPS which has
the tracked route stored in it and my by extensive knowledge of the area. I
also confirmed I was directly over Bridgeport and flew in-between the lakes
in the area if anyone is familiar with them. The controllers insisted it was
me and said he tracked me flying over Westchester, I'm absolutely positive I
was never in the area. He got alittle agitated when I told him I believed I
was correct and he just demanded it was me for sure. I'm just curious what
anyone else would do in this case. Another aircraft came into Danbury around
the same times from the south and I think this is a case of mistaken
identity and was accused of busting the class delta for no reason. Are there
any actions or steps I can take against being falsely accused?

Thanks,
Chris
