They call 12-22 times daily as "unknown"
I finally purchased TrapCall & now I can block unknown...but not for long because they change # to 975-964-2877 or 229-518-6462. The few times I have answered they instructed me to go to my computer to fix a Microsoft program. My protests met with snide remarks, foreign accents....
Got a call 2 days in a row at exactly the same time from some idiot identifying himself as "James" and saying he had important papers to serve me. When I answered the call the second day (the first day I let it go to voicemail) and questioned what the papers were he got huffy and super defensive and said I should know exactly what they are and that he'd be at my residence in 2 hours to serve me. I laughed and said ok I'll be waiting for you ***hole because I'm curious to know what it is and he promptly hung up on me. Don't buy into this garbage because its obviously a scam. I've filed complaints with my local police dept as well as consumerfinancial.gov
For me it was First Premier bank about a past due payment. The number is fake, but at least for me ,it was a legitimate call. I wouldn't give info to them, but called back their cust service number. I asked why they use fake number, didn't get a response.
