Who called from 2407202202

Caller ID said Gaithersburg MD. I don't know anyone in MD. No message left on machine & this is not the first time I've gotten calls from this number. By the way, I am on the dnc list....a lot of good that does me!

i called the number back and they said I was called 15 and I won a cruise out of Florida

I happen to be home when this call came in so it was immediately blocked using my call Blocker device. I have also blocked the area code.

It seems that once they realize a number is blocked they are using different phone numbers to try and get through.

Since I can block entire area codes also,  they have less chance of getting through on any number.

I do not answer any call that I do not recognize.  it is immediately blocked since 99% of the calls coming in on my landline are scammers.
