Who called from 4153639787

I keep getting a call from this number 415-363-9787 when i pick up the phone they hang up.
whats up with company?  they do it every morning

I receive calls from them all the time. This evening David informed me that he was going to send out free upgraded diabetic supplies. Like Madrat, he referred to working with my insurance. He asked for my insurance information, that flew a red flag imo. I asked why I wouldn't use my mail order pharmacy and the line went silent. If working with my insurance he should already have my information, all should've done is confirmed my info.  This could be a scam to bill your insurance.

If this number calls you, file a complaint with the National Do Not Call Registry. Let law enforcment deal with them! https://www.donotcall.gov/default.aspx

I have received at least ten calls from this number.
They never leave a message.
Annoying

What was he going to do, hold you down and do your hair?
