You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.

Example input: Although I did enjoy the food here, I was completely unimpressed (and slightly annoyed) by the overpriced margaritas.  I ordered a platinum which contained \"fresh\" juice.   It tasted like it had sprite in it, so I thought surely she gave me the wrong one.   It turns out that \"fresh juice\" is really margarita mix on tap from the same gun as the sprite.   I asked for something fresh to replace the horrible margarita and received a rocks glass with just muddled lime and a salted rim.   I'm not sure it contained any tequila.   Horrible!   It's not that hard to make a fresh margarita!
Example output: 2 stars
Example explanation: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.
Q: Horrible customer service.  We had our patio sliding door replaced with french door, they installed wrong door with wrong size the first time, then the second time it was wrong too for open on right vs left.  It took over 3 months for them to get it right with no apology.  We couldn't do anything because they took our old door and trashed it; thus, we couldn't even have it back and go elsewhere.
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
