XR screen issues with multilple attemps

i have an iphone xr it Had a cracked screen. i replaced it and the touch doesnt work properly.. i got another screen and it randomly stopped out of no where. i tried putting the cracked screen back on and i ripped the cable. i dont have solid income and have already spent more then ill be able to make selling it. theres only a few options. try and get a refund on the randomly broke screen, someone tells me how to fix touch error, i do nothing and cry. also how should i keep it while im waitiing for a new one. because trying to take the screen off is what ripped my ribbon cables but im scared if i dont then the inside and the top camera will get stuff on. please give advice im in need of it
