Reverse phone number lookup prefix 830-240

I keep getting calls from all these numbers in spite of being on the Do Not Call list since 2004. I haven't filled out inquiries on websites for this stuff but they try gaslighting you into thinking you may have. It's blocked. Do know the number. Not answering anymore.

Unsolicited SCAM or FRAUD caller refused to identify self and would not state purpose of call. This is the 1254th call from small towns this year and the 10th from Carrizo Springs, all from different subscriber numbers. I know nobody there, have never been there and have never done business there.

I like to report it a spam

Received threatening voice message from 830-240-8526. Will be reporting this call.

Telemarketing/spam caller acalled but did not leave message and hanged up, I told several of these callers not to call at least once and sometimes twice but they keep calling.

Called asking if I had life insurance and he was recording my voice. DO NOT ANSWER CALLS FROM 830-240-8191.

Popped up a couple times today on my office cel phone, which is on the Do Not Call list, from Carrizo Springs (a sure clue that it's a spam, since so few people live in that tiny town, and 80% of the spam I get shows that it comes from there).

Never applied for a grant.

Unknown caller. No message left.

Caller says he is with IRS and filing a lawsuit against me. Get a life.
