This company keeps calling my phone even though I have repeatedly declined to take their survey. They have several different numbers they are calling from because each time I block a number they call back pn a different line. My number is registered on the Do Not Call List, and I have filed complaints regarding this annoyance, but it doesn't seem to matter.
Recorded message claimed to be calling for a short 30 second survey. When they added that for participating, I would have won a free 2 day cruise to the Bahamas, I hung up. Scam
The didn't "get" your number, they just start at 000-000-0000 and dial every number up to 999-999-9999. With digital dialing these days, you don't even need expensive equipment to do that anymore.
