What four-legged partners? Did I miss something

These are the different stages Anja & I went through after opening our mailbox upon our return from the gym. Here comes the explanation:
We live in a former American housing area, which was bought by the City of Frankfurt when the majority of GIs left after the Reunification of our country. As Anja works as a nurse at a hospital which is completely owned by the City, we qualified for getting one of those appartments at a very reasonable rent. As those appartments are kind of subsidized they check from time to time wether we still meet the requirements for paying that relatively low rent. The first years we were considered newly-weds and qualified, but now that's over and we have to pay an additional rent of 169 ($204) per month

But the 'best' is yet to come: The letter states that this raise started at 02/01/04

So we have to pay them 1183 ($1430) immediately and 169 monthly starting 09/01
My parents who got a similar appartment, because my Dad is a federal employee, have been paying this amount now for 10+ years. So I checked it with my Mom, scrutinized all the calculations and guess what: Everything is correct -
I HATE SURPRISES LIKE THAT!!!!
We wouldn't have complained if they had sent the letter in time. Say in January with the payments starting in February, but not that way. Additionally they sent that friggin' letter on a Friday, so that you can't call them and complain before Monday!!!
The money we will be paying is going to be used to support people who can't afford decent appartments otherwise or to build new subsidized houses. I do think that this is OK, as we have quite good salaries - but their timing
SUCKS
OK, I just needed to vent a bit

The big venting will come Monday - when I call those bureaucrats.
