Lower your credit card interest. Call again and again, from many different phone numbers. Keep blocking and keep calling the FTC, FCC and FBI. Wish someone could take care of them, once and for ever.
It's a text message with a link that looks like a local address. Fortunately I know the area and know that the address is fake. I will not open the link for fear of a virus being attached.
This moron calls everyday 3/4 times. I am blocking the number as of this moment.
