This number calls immediately after another number from the Tacoma area with the same area code. This annoying phenomenon started last week.  Less than 2 minutes ago I added a comment to the long list of comments on the number 253-245-2353.  I do not know who or what they are as I do not answer and they do not leave a message.  They are contacting my home phone and are not leaving a message.  

Second day we received a call from 253-753-9461.  I do not answer unknown calls and they left no message.

Received a call today from this number.  I didn't answer and they left no message.

ROBO call.  253753-9461 calls our business about "home security systems".  It's very annoying and we're on the Do Not Call list.  

I also get these calls.They leave no answer when I pick up.I am on the DNC List
