This sounds very fishy to me - there are lots of scams going around.
Did you have to give any of your personal info on the request? Like your social security number and/or your bank account number?
Do you know whether or not the claim was even correct - i.e. that you are owed money??
I think it is good that you contacted the AG but if you did give out any of your personal info on the request like your SS # and/or your bank account info - you need to also contact Medicare Fraud Unit. Also make sure that your bank account and social security account is secure - same for your credit.
This is kind of old but scammers sometimes just redo old scam and put them back into service again.

I hope I am wrong but unless you are assured that the "refund" is substantiated by the insurer and you understand the problem - then it could be a scam and you need to protect yourself NOW.
