Replying to Delete this if you want, but I need to RANT!

Alright so basically my brother totalled my subaru back in June while I was on a cross country trip. I had been looking for a decent car all summer (I didn't really need a car till closer to the end of August, so I was taking my time). And in the BEGINNING of August, my neighbor had a great deal for me (1999 for Explorer for 3500, amazing condition, one owner, only 80k miles) and the only stipulation was that she needed to find a car first, but that would only take a week or two because she had also been looking for a month. So about a week ago (way past the expected date, but still not entirely rediculous, though she did keep saying one week and it turned into a month), she says, its definitely going to happen on Monday. So i get a call at 10:00 tonight (sunday) and she says she has no idea if she wants to sell it now and she'll let me know tomorrow. WHAT THE FUCK?! After being strung along for a month AND THEN saying its a sure thing a week ago, I all of the sudden have to just look for a new car AGAIN and its too late. Are you fucking kidding me? I understand people have their own agendas, and it is entirely in her right to not sell the car, but tell me that your not going to sell the car! And she knew that I needed it by basically now and still didn't even have an apology. Like come on, its just a matter of common courtesy. People are so fucked sometimes. Thank You.
