They call and hang-up from time to time. Always turns out to be a fake charity or cruise scam targeting seniors, or something else like that. They may call from a spoofed number later. Probably got my number (and yours) from our greedy phone companies that sell our info. on lists to anyone who can pay. Banks sometimes do this too. It is good for their business.
Just got a call from 757-414-9327 Didn't recognize the number so I did not answer. They didn't leave a message so I figured it must be a scammer. I blocked the number The END !!!!!
