What a drag! Sorry to hear what you're going through. I just got a call with your number showing in CallerID, which I didn't answer. The bad guys have likely made your phone number unusable for you and I would think you'll need to get a new #.
There's got to be a way to come up with "certified" caller ID #s that can't be spoofed. Until then, I'm using blacklists via Ooma to filter my calls, but many still slip through to ring my phone like this one did. I may switch to whitelisting via Google Voice, so only the numbers I approve will make it through to ring.
I'm sorry you are going through this. This is a perfect example of why people should not call unknown numbers back. You never know who is really going to be at the other end.
In the past telemaggoters used spoofing in order to display out of service numbers, however there has been a huge increase in those that display numbers that belong to innocent people.
Your one of the reasons why we don't encourage people to call back numbers since they are creating yet another victim of the spoofing! I've added this to my notepad so I can use it for teaching purposes here. thank you for coming foreword with this!
