the mail man always mess up the mail delivery

you should complain the mistake that mail man have done by phone or mail.
or may be the mail man just is new,you should talk to him as kind and tell him that he has failed to deliver

exactly. what if it is important mail? I've had that in the past. I remember one guy buzzed for 30 seconds to get in the flats so i let him in and the idiot gives me a letter that's further down the block

I mean I'd thought you should be able to read before giving a job. Not to sound mean but Identity theft is a real problem and it is absurd. It's not hard to do that job right. It's not hard to look at where your going and reading the address properly

The world is full of thieves and people who like causing problems sadly - and some who may not care much about others property

Goodluck

yeah,they should responsible for the lose if it happens,you should inform the post office again what your address is.tell the mail man that he delivered to the wrong place .
