Who called from 8722102024

Calls our chain store over and over, multiple times a day for a few days now.  No answer on the other end and they never leave a message.

I receive this call at least twice a day, every day and  when I answer, no response from the caller, even after saying hello several times, and I am on the do not call list,

Keeps calling but if I don't know the number I do not answer

They call a couple of times a day. When I answer there is no one there. When my phone dials them back, it says the number is disconnected.

Got this call this morning........answered and there was no one on the line......Don't trust calls like this.
