I’m exhausted from dealing w/an older friend’s susceptibility to being scammed. Good rules of thumb: • Don’t answer phone calls from numbers that aren’t in your contacts. That’s what voicemail is for & remain wary if they do leave voicemail.• Don’t respond to emails about your whatever is about to be shut off if you don’t update your payment plan. Check your accounts, contact your vendor if needed but bypass the suspicious email.Remember: these people are guilty until proven innocent.
