"Free" topical pain cream scam.
Boiler room call from criminal scum named "Lin".
Caller ID shows: RELIEF4PAIN
They call about once a week, always from a different spoofed number, so blocking does no good.
When I tried to find out the name of the company calling it was mumbled and changed each time I asked her to repeat.
Look these cream scams up.  They are either worthless or dangerous and they try to bill your insurance for 10s of thousands of dollars for a one month supply.  These scum have been scamming insurance and the government (veterans) hundreds of millions a year and growing fast.

TeleTerrorist!  Fake id 'relief4pain' = Blocked.

Caller ID = "RELIEF4PAIN." I answered, guy kept saying "hello" and I kept saying "hello" back to him. After a few iterations of that, I hung up. I wish there were a "relief 4 pain" caused by telemarketers.
