NEVER call back ANY phone number unless you know who it is!
Calling any of the scammer numbers may only cause you ENDLESS problems with more scam calls!
Remember: If a caller is legit they will leave a message and that message will be meaningful.
If they do not leave a message it must not be important.
If the message means nothing to YOU, then it's also not important.
The carpet cleaners, who are really all about stealing $$$. This scam has been around forever, and the numbers just keep changing. We always gets the scam calls in batches. Have had 6 in the last hour (most of them were blocked). The carpet cleaning scam ALWAYS seem to call around the time that the credit card scammers call.
