Who called from 3137499029

They are horrible and relentless!  How do I stop these calls?

No message was left but I called the number back and it was a recording from a telemarketer.  I removed my number from their list (hopefully)

Got a call from this number yesterday. There was a delay after I said hello which is usually indicative of a telemarketing auto-call. I hung up and then blocked the number.  I have received an onslaught of telemarketer calls since I subscribed to Freebies.com.  Do not sign on to Freebies.com unless you have no problem with emails and phone calls from companies.

They call three times a day

These  telemarketers keep Badgering me two to three times a day even after I insisted twice that they remove me from their lists.They won't stop calling.
