I recently became eligible for Medicare, and as such asked AIM to cancel my plan effective 3/1/2010. They took money from my checking account for the months of Jan 2010, and Feb 2010, but cancelled my plan effective 1/1/2010. On April 21, 2010, I contacted them by phone about this, and was assured they would send back the 2 months premiums. As of May 24, 2010 they have not done so. I found out about the cancellation when they denied payment for a mammogram in Jan 2010, and sent an EOB stating I did not have insurance on that date. My broker is having no luck in contacting them and I have not been able to get through to them by phone since April, 2010.
