Four calls in less than 90 minutes this morning! Appears to be same scammers that have used other spoof numbers and sometimes toll free numbers. If you call the toll free numbers back and get someone to answer it is the same guy that calls from the spoof numbers. Call center is outside US - probably somewhere in Asia. Calls started when I had to change phone carriers and so far there have been 10 different phone numbers in 4 months. Main thing to remember is never answer a call you don't recognize. If it is legitimate they will leave a message. Save the number in contacts and assign No Ringer. I have also removed my name from my outgoing voicemail. If they can match a name to a phone number they can sell it to other scammers.
I'm also getting calls, up to 10 times a day, sometimes very early, and very late. I tried to do what Krystal said w/phone ringer but my phone doesn't have that option. Going to report/list number on the Do Not Call complaint form and hope for the best. Wondering when/if it will ever end, been going on for a long, long, time, can't even answer my own phone (home or cell).
