Call your local police and file a report, I was receiving hang-up calls from 3000 miles away twice a day at the same time of day every day, and when I called their local cops, they told me to call mine. I did, they got a hold of their phone carrier, calls stopped and they told me if it happened again to tell them and they'd file a formal complaint. Most of these are scammers and thieves, but there are also huge mainframe computers that are not being maintained to save money that robo these calls with no intention of making contact. And I do not have any "ins" with my local police, and most of them are not even very nice. So if it worked for me, it will work for you.
Missed the company name but they claimed they were collecting on behalf of St Jude's Hospital. Told them I'd send StJudes the money directly instead of to a telemarketer that skims most of the money.
It is not human dialing this number, most likely automated computerized call until you pick up, then starts typical pre-recorded marketing sales pitch.. I have placed this jackhole in my phone's reject list!
