Change of address hassle..

We changed our address at the post office a few days prior to moving... I understand that it sometimes takes a while to get mail that needs forwarded to the new address however, Mike was supposed to get his paycheck 2 weeks ago! And still has not received it. We have called the post office and gone to the post office and no one seems to know where it is. He checked with his work to make sure it wasn't returned (which it wasn't). Then the tell us that not all of your mail gets forwarded... Ok, so who decides what gets forwarded and what doesn't?! Then to top it all off he was supposed to get another paycheck yesterday and it didn't come... So basically he hasn't been paid in a month! Hopefully it comes soon or Mike may lose his mind!!
