Who called from 5135651243

I called back.  A message said it was a non-working number.

Answered but no one was there.  Sound like a robocall.

Do not answer these calls, and we don't call them back.  We are on the do not call registry and they are calling on our cell phone.

REALLY DAMN tired of these stupid calls to my personal phone.  AND, that is right - you can't call back to get it removed, or anything.  shouldn't be allowed.

I answered the call. Supposed to be a heart study to see if there has been reactions to either blood pressure or cholesterol medications
