Who called from 3144499980

just got a call could not hear anyone..  The entire time i was saying hello my phone was still ringing.  I hung up and blocked the  number.

This number is busy today, they called my phone but I wasn't around it.  Saw I missed a call, they did not leave a message

This number called my landline 314-449-9980 and left no message. I also got a number 314-601-3275 the day before, same results. I checked the numbers on spydialer.com and both numbers are coming from the same location. 536 N 9th St. St. Louis, MO. Still trying to find company name or building name.

Got a call 2:18 pm, 1.26.16, south St Louis County.  Did not pick up. No message.  They've called before. On do not call list!

Called today, 1 minute prior to getting another unknown call from an Ohio number. Whatever it was didn't leave a voice mail or call back a third time.
