Sorry. Disagree. Call blockers do work. You just need one that will block area codes as well as individual numbers. I have every area code that I know no one in blocked & then of the ones I do, as well as my own area code, I have the unused prefix blocked. They call, they get blocked, the calls start to slow down & then you get a couple a month. It works. You cut off the calls & you cut off the money & the scammers call someone else.
WARNING--BEWARE!! These callers are B I G credit card criminals, known as the card service scammers! Under NO circumstances, give these lowlifes your credit card number, or you will regret it forever!
Called telling me they are with my credit card company, but couldn't tell me what company and then called me a dirt bag... my response was thank you and have a nice day.
The card service scammers WILL 'service' our credit cards, BUT, when they finish 'servicing' them, they will have NO available credit remaining! People that are fooled into having their cards 'serviced' will be charged a MINIMUM of $795.00, and many times the ENTIRE amount remaining on the card. The card service scammers are a disgusting group of degenerates, who prey mainly on the low income, and the elderly, but will cheat anyone that they can!
