About 7 months ago i purchased my hp laptop from walmart, about 2 months or so into owning it, it started shutting down unexpectedly so i contacted them to fix it. They went into my computer and turned off many processes which caused some of my programs to not run when launched. I tried getting them to undo the changes and they said if they were to go back into the computer they would need to charge me an additional fee

Why should i pay more money to fix their screw up? All i want is for them to undo the changes and i will figure out how to resolve the shutting down problem myself.

I was passed around 6 different times to just be told there was nothing they would do unless i payed more money for something they screwed up.
