Who called from 2063945000

I have been recieveing a phone call from 206-394-5000 every 20 min for the last 48 hours and T-Mobile wants to charge me $2.00 a month to block this number. WOW!!!!

This number has been calling our Spring cell phien for almost two years.  At least 20 times a day.  We have complained to Spring who days thyey need a police report and the then the police say that's ridiculous, tell sprign to block the call.  Is there nothing we can do?

This number has been calling our Sprint cell phone for almost two years.  At least 20 times a day.  We have complained to Sprint who days thyey need a police report and the then the police say that's ridiculous, tell Sprint to block the call.  Is there nothing we can do?

It's not just cell phones that get these solicitation type calls, it appears to be a "ghost" fax machine. We get them on our land line as well......
