And you got what you got… it hurts, but you didn’t do enough that is painfully obvious to you (when you remove the emotion) and us (which is why we see it differently)…
What you think they should do and what you think is the right thing for them to do is immaterial to them at this point… I can’t believe that will change either…
I realize and knew from the start you bought what you could afford, and for that reason alone should have required that you to do more leg work and research so you could buy a better unit in your price range… believe me you could have done better in any price range, but it requires you to do more and better for yourself… not always easy, not always quick, but always doable…
Again I wish you the best, think about and consider selling and replacing before you get to far invested into a dwindling asset, even after the repairs… when the hole is to deep stop digging…
