This is a Spanish speaking person calling and I don't know Spanish.  Where did they get my ph. no.?

They speak Spanish and no English.They have been calling my business line for months.

Dont answered is a fake call

Same here. Because of the language barrier I cannot figure out how to stop the calls.

Modern technology has given telescammers the tools to call you.
Since those telescammers are criminals, they ignore the Do Not Call list.
Modern technology can also protect you, if YOU do a few simple things!
The first thing to do is buy a call blocker device, service or app.
Then, use it correctly.

Google "call blocker" for more information.

If you cannot afford or use such a tool, then:
* Do not answer calls from unknown numbers ... let them go to voicemail or answering service
* Do NOT return calls from unknown numbers!  All that does is verify your phone number!  And, in some cases, those return calls may cost $20 or more to complete.
