Tablet Screen is broken... And extended warranty?

Recently, April 26 of this year (2019) to be exact. My tablet screen cracked from the inside to the point of the screen being almost entirely broken. The screen still responds to touch, however, I am unable to see anything at all. I called today and I was told that due to not purchasing the extended warranty right when I bought it. it couldn’t be fixed without it. So I ask if there’s a way to purchase they extended warranty and I was told I couldn’t. (This is peculiar considering that you would usually be able to purchase some sort of warranty with other electronics) I don’t want to replace the tablet due to having files on it that are on the apps I use, for example Ibis paint art files and voice recordings I made. There’s no way I can retrieve those files due to them being on apps (believe me I tried using a relative’s tablet to do so by logging into my app store account. And the files weren’t backed up on the app whatsoever.) So my question is, is there any thing I could do to fix the screen? Like I said, replacing the tablet wouldn’t be a problem if I didn’t have files on it that I can’t retrieve. Help please??? It’s a Prestige Elite
