My friend left my number late, just started calling, and now I send a message every three or two days. It has an unsubscribe reply T. Is it useful?

In case it expires, it is useless to unsubscribe from this information. After a period of collection, if you can't receive it, you can only change to another collection company to continue, otherwise you will receive a text message or a phone call. You can call a customer of a financial company or bank and ask him to delete your contact information. You can tell the dunner that you didn't know when you left your contact information. If you don't delete it, I will choose to call the police because it has already constituted harassment. I hope it can be adopted. Thank you.
