Is this finally settled?

Since I moved I've been fixing and settling little details regarding the apartment where I live now.  Each time I do something, I do it believing it's the last thing to finally get everything done, but over and over, I'm being proven wrong!

Last week I changed my address in my driver's license and advised my embassy too.  After that, I had to change some freaking lightbulbs which in this country are of poor quality and burn out after only one month of regular use (in my experience).

Then came the electricity non-payment notice!  How come I just moved in and I get this?  Surprise surprise, the previous tenants didn't pay their bills for who knows how long, and now it was the last notice before they actually shutdown the electricity.

After I got that solved, again some more lightbulb problems!  And when I tried to change by myself the lightbulb, the socket broke (never seen a lightbulb socket break, but in this country, it happens).  So I need the building's technician to fix it for me.

Okay okay, so fiiinally!  Everything is settled, right?  Wrrrooong!!!  A few days later I get my first electric bill, but the measuring cycle spans only 10 days that I've been there, and 20 days that belong to the previous tenants!  And the grand total is a fucking sum that those jerks must've had the aircon constantly running... I can't believe it, especially when I only use the electric fan!

So I went to talk to the girl in the management of the building.  Unbelievable they didn't take note of the gauge's reading for the day I moved in!  So what am I going to gain by getting angry?  She proposed we split the bill half/half.  But hey, I've been here only one third of the billing cycle, and even then, I only use the fan, not the aircon!  At the end, we split the bill 1/3 and 2/3.  It took her forever to understand the logic (she wasn't trying to cheat me or anything).  She's got good intentions, but she really is in urgent need of math classes.
