Can the postal service for reminders be intercepted?

Rejection is a futile exercise.

As a debtor, if you want to reject the collection letter, the purpose is not to recognize the creditor's claim, and try to use the rejection to extend the statute of limitations so that the statute of limitations will expire as soon as possible. This is futile.

The creditor will ask for a return receipt when delivering the reminder notice, whether it is delivered directly to the person or delivered by registered mail at the post office. If you refuse to accept the letter, it must also be recorded in the post office's register. Sign the "refuse to sign for the letter" so that the post office will have an explanation. Even if the creditor delivers the document in person and you don't sign for it, it won't help, because the creditor will go to two people, both of whom will testify at the same time that you did not sign the document served. The proof in this regard will fully prove that the creditor has claimed the right, and it will not help if you do not sign.
