回複：氣憤，收到 CBCS 的信。

You still can go to post office to change your address.

You can call them again. You have the right to know what it is before you decide if it's yours or not. Do not promise to pay, don't give them any info about youself.

For those kind of money, the only thing they can do is keep sending you lettles.

Anyway, find out what it is first.

Good luck.
