SoundPoint Audiology and Hearing

I scheduled an appointment for the free hearing exam. Received a phone call the day of my appointment telling me that the Dr. at their office can not see me because she does not except my insurance. I asked why do i need to give you insurance information if it is a free exam? She said in case I do need hearing aids. That just dont sound right to me. Its the free exam is what i wanted to find out if hearing aids would help me.
