Who called from 2102808487

I keep getting calls from this number; cannot call them back, they hang up.  How do I block this number from bothering me.  I am on a do not call list.

I have this number ( 210-280-8487 ) call me at least once a day.  At first it would go to my voicemail and say something about not being able to connect.  Now I just ignore the call.  I dont know anyone callin gfrom this number and where I live in Canada and this number is from Texas I am confused.

how coincidental i just received a call from this number also today twice and when I answer there is no one there I assume also a scam so just deleted the number.

I have been getting calls from this number for a few days....very annoying

this number has called me 4 times over the last week.  They ask for me - apparently I had requested information for a home business - DID NOT.  Now I just ignore them, they go to voice mail and leave no message.  Funny how they got my name and number when it is unlisted and I am on the do not call list!
