They KNOW they’re spam calls. They KNOW the uncheckmarked numbers are not valid. So why the hell do they let these calls through? Anyone know?
My carrier (Telus) here in Canada has a great feature called Call Control. If an unknown # tries to call me it prompts them to input a code on their end to verify they're human. I literally get no spam calls. Ever.
With this feature I get to add 20 contacts as a whitelist who call me often and I verify.
