Real estate hell

I had the worst time of my life trying to buy our house we just closed on the 28th. We offered our first offer back in MAY!!!! She would accept an offer then close it out and ask for more money she did that 3x. I am now 39 weeks pregnant and the whole carpet had to be ripped out the house needed to be repainted. The house had been smoked in (weed and cigarettes) since the last time we saw the house because she left her teenage son to live in the house over the summer while we were fighting tooth and nail to get into the house. Our first offer was a lowball at 160k but she got it up to 198k last offer. It’s not a gorgeous house but it’s on 2 acres and it’s next to my mom in the country so it was a perfect investment in our family and future. When we signed Thursday her and her realtor refused to give us the keys until recorded we got the go ahead that the recording was processed 530 Thursday night. We reached out they ignored us. So we just broke in 🤷‍♀️ (mind you I need to get this whole house renovated in less than 10 days so those few hours mattered) when we got there we realized she had taken a single battery out of each key pad for the front and back doors and both the garage entries. She locked the door handle locks and then she bought hotel room locks the ones that flip back and fourth so you can’t open the door all the way and she locked front and back doors like that then I’m guessing left out a window so we couldn’t get in. It’s 330 on a Sunday and we still have not heard from them to get the keys from our house. She came Thursday and got her for sale sign AFTER the sale was processed and recorded and still didn’t leave us the keys. We sold our house to get into this house and so we were practically homeless waiting for this sale to come through (we were staying with my mom) but as I mentioned earlier it’s my mom’s neighbor so we have known her for YEARS she knows I have two young boys and I was pregnant she was a terrible person to work with I cannot believe the things she did knowing that my kids wouldn’t have a home to go to at night or that I might not be able to bring my newborn home into his own house when I have him. She left the house disgusting nothing wiped down nothing cleaned she left her trash there rugs she didn’t want beat up old furniture a disgusting stained office chair her adult son was gaming in. Dog poop all over the backyard. She also went to the electric company on Thursday and begged them to turn off the utilities as soon as possible and even offered to pay them extra if the city disconnected them THAT day instead of just letting us transfer them into our names on Friday morning since it wasn’t recorded until 530. I went into the utility office to transfer on Friday morning they told me all of this told me they couldn’t get utilities back on until Tuesday due to the holiday weekend. I broke down in tears they had someone go out at 6 that night and turn them back on haha I felt like an idiot but this lady has just done her absolute best to try and make this as hard as possible for us to do this and I DONT KNOW WHYYYYY!? We are young and this is only our second home buying process but are there just bad people out there that are willing to treat people like this for no reason or did we do something!? I can’t imagine doing to anyone what she did to us. It’s heartbreaking.
