Annoyance of the Evening

The good news:

1. Our sink has water pressure again!  Two years ago, just after we took over our apt lease from P's brother, our sink exploded.  It leaked into the unit downstairs.  All of the pipes had to be replaced, along with the cabinet.  Our water pressure has been nonexistent ever since.
2. The sprayer also works!  That hasn't worked since BEFORE P's brother moved in (which was about a year before us).

The bad news:

1. As you can see, the cabinet that was installed in place of the old one (about two years ago) isn't an end cabinet.  It's a center cabinet.  Can you see the MDF that sticks out like a sore thumb?  Any suggestions on what we should do with it?  We thought about tiling it, but I think that might look weird.  We don't have any tools to cut a piece to fit the space, though Home Depot could probably cut us one.  Also, the cabinet doesn't match the rest of the cabinets.  The rest are white.
2. After replacing the cabinet, there was a VERY large gap between the new countertop and the existing drywall.  The "repairman" used spackle to try and fill the entire half-inch gap around the wall.  He then painted ONLY THE SPACKLED AREA with paint of an entirely different color than what was on the wall.  We ended up painting the entire kitchen as a result.  We like the orange.
3. The man who fixed our sink (this was the third attempt at doing so, btw) took two full nights.  I watched a DIY.com video, and it took the man in the video five minutes.  He bought the cheapest fixture possible.  Also, in process of fixing the water pressure, he managed to soak the entire bottom of our (relatively new) cabinet, get some substance on the lovely orange wall that won't come off, break something glass (we still haven't figured out what that is) and he switched the hot and cold lines.  So, the cold knob is hot, and hot is cold.  Neat, huh?!
4. Our cats have had to be locked up for 28 hours straight in my office.  As of last night, there were chemicals all over our kitchen from under the sink.  (Method, here we come!)  Also, they cut a very large hole in the side of the new cabinet when it was installed for the pipes to go through.  I am 100% positive that given the opportunity, Sheila would have been back there, lost forever in the bowels of our kitchen.
5. The original call to our landlord was because one of the ceramic knobs on our bathroom sink broke in P's hand.  He had to go to the emergency room to stop the bleeding.  They still haven't fixed that sink.
