I get these scam calls too [...]. I have an iPhone and I usually have do not disturb turned on. I set up a list of contact exceptions that will allow these calls to come through the DND block. All other calls get blocked so the scammers never get through to me anymore. I can understand tho how something like this can trigger your anxiety. I can also normally spot the spam calls a mile away so when I do answer, the call gets an immediate click. LOL
I ignore and laugh mostly at stuff like this, even tho it is annoying.
