Who called from 7862336646

Called, hung up before I answered. I called back several times and only able to get a busy signal

foreign language person named Lien.  Hard to understand.  said she was a representative of Medicare and that I was eligible for a back brace.  Said it was free but I couldn't believe that so I told her to get permission from my doctor to receive the brace.  I didn't leave my7 doctor's name or number.  Figured that if they knew I had back issues, they knew my doctor!

Another "scammer".  So very sick of these calls targeting elderly Medicare persons.
