Hangs up when answering their call.

Caller ID says ILS Health. Another unwanted call. When will it ever stop?

this call is from independent living services-they are a company who sends free meals to elderly, or people who recently got out of the hospital. they are a food service that humana uses (i know this because i was recently hospitalized, & humana called me to see if i wanted the free meals, which i did, & ILS called me from this number to make sure i got my delivery & to see if everything was ok with the meal choices
