To be honest, I find scam phones more annoying and irritating than scam emails. (Though you hardly get those if you live in the states or in Canada) Back when I was studying in college in Taiwan, I've gotten countless (yes, countless) scam phone/phone text saying how I 'owe' some bank money and that I should immidiately return the money or my bank accuont will be frozen. The first reaction of most people is usually "Huh? I don't owe the bank any money, what are you talking about?", then will give you a phone number and tell you that
you've been scammed and you should phone that number which is supposely the police station. Oh the irony! Then once you call the "police station" with the number THEY provided to you, they will ask for your bank info (ie your bank account #), your personal questions etc (phone, address, name...) and eventually they will get a hold of your bank info etc and get the money.

There are also alot of other scam phones like "Congrats you just won this random lottery!" and there are even more ridicuously ones like how someone would phone you and start screaming "HELP ME MOM/DAD (depending on the voice of the person who picks up the phone) I GOT KIDNAPPED" and threaten you to pay or they will kill 'your son/daughter' that you never had.
Jam it back in, in the dark.
