I was writing a complaint on the do not call registry when they called. I never answer, but I did to help fill out the complaint.  He said he was from the Philippines and the number is auto-dialed.  He said he wasn't selling anything, but wanted to inform me what is available through my health coverage.  He said I could google "Healthy Blends" and follow them on Facebook.  He said it was a pharmacy and mentioned something about Tropical.  I kept telling him I wasn't going to do any business with him and told him to stop calling. I asked why they didn't leave messages, but he just kept trying to recite his sales pitch saying "my message is…" He finally hung up. I just don't get it. He wasn't asking for any of my info, but he already knew my name. Why would anyone listen to them let alone do any business with them.

I have received phone calls for the last several days from this number. As this is on my cell phone, I ignore unknown numbers.  When I try to call back I get all agents busy and the line then disconnects.

When I answered they hung up - so annoying. I am on the Do Not Call Registry

These guys keep calling and not andwering when i say hello then they hangup is this some teenage prank

I get calls, all day long, from numbers I do not know. Unknown, and even private numbers. Funny thing is, they call, one right after the other. Sometimes, they'll call from numbers I have blocked. Then call right back with a private number. Then from this number.
If I have to enter the same number, a 2ND time to block it, that usually works.
Oh, and the Do Not Call Registry, does not work.
I once worked for an insurance company in Garden Grove California, that only preferred to call States other than California. This was an auto/boat/motorhome insurance carrier.
I would add a person to their Do Not Call list, just for someone else, to get the call rerouted to them, and they'd call the person.
Report, report, report. It Is possible to get their phones confiscated and service shut down.
Call your service provider. Lodge a complaint.
