Market Smart Strategies review: medicare open enrollment

Received unsolicited mail from
market smart strategies
po box 1009, carmel, in 46082
requesting information - name, date of birth, phone number, also the same information for my spouse

Mailing indicated i could be missing out on entitled medicare choices and benefits.
I google the company name, they are just and insurance company trawling for customers, they are not connected to Medicare Enrollment or Benefits
