Bridgecrest review: Why are you calling me a day before payment is due?

Not understanding why would I receive text before bill is due. And then a letter next day if though my payment is several days late I have a 2021 Nissan value at 8000. But finance was 34thousand what a fool I was but I needed a car. But to take advantage of someone like that the car triple what it is worth payment are almost 700 month I feel so stupid. I can not even finance the car because I'm so upside down . Someone reading this have any suggestions what I could do please helpm
