The scammers in foreign country's have not got a clue how our laws work really. Debt is a civil matter and you can not be arrested for owing a debt. Below are the laws, and other info in regards.Know your rights! Demand a legal address, demand a debt validation. With extortion scams, file reports with all agency's.  You may want to consider a call blocking device or phone also. The T-lock Incoming PRO Call Blocker sells for under 60 bucks on Amazon and can block up to 1500 numbers.

A debt collector may not communicate with a consumer by post card. It may not use any language or symbol, other than the debt collector’s address, on any envelope when communicating with a consumer by use of the mails or by telegram. A debt collector may use its business name if such name does not indicate it is in the debt collection business.

If a consumer sends a written §1692g response within 30 days, the collection agent may not communicate with the consumer until it mails the consumer the requested verification of original creditor's name and address.

A debt collector may not reveal or discuss the nature of a consumer’s debts with third parties other than the consumer’s spouse or attorney.

Bills.com FDCPA FAQ

Below are questions Bills.com readers ask frequently:

Can a Collection Agent Call My Cell Phone?

Yes. However, if you tell the debt collector it may not use that number because it is a cell phone, it may not contact you again at that number.

I Keep Receiving Dozens of Calls From Collection Agents. Is That Legal?

No. Unscrupulous collection agents will use "block parties" or "office parties" where they contact a consumer, multiple neighbors, or co-workers telling them they need to reach the consumer on an urgent matter. This is not permitted under the FDCPA.

A Collector Says I Will Be Arrested if I Do Not Pay

This was a true statement before the US Civil War, but has not been true since. People may be arrested if an aggressive judge files a bench warrant for a person who does not appear at a hearing relating to a lawsuit regarding a debt. However, in that case, the offense is the failure to respond to a court order, and not the existence of the debt. As stated above, it is illegal under the FDCPA to threaten a consumer with arrest if the consumer does not pay the debt.
