Hello, Why did the Post office return my mail to the bank as Returned mail (undeliverable?)? Because of these bounces three times. I did not know the bank was trying to get in touch with me. On an account that I did not use much and was overdrawn. Now they closed my account and took penalty. Why with the correct address did the mail return to the Bank and not me? I lived all my life at same address and i'm not that old lol. Yet some mail from the same bank came today normally. What do you mean fluid? Thanks I should not had to pay for post office equipment failure to my Bank. They raised the over priced mailing rates so they should raise the delivery standards.
