Original Screen S20FE

Hello friends! The famous green lines appeared on my screen. I bought the refurbished cell phone last year. I fixed the screen in April of this year, a cheap $30 one, and well, I can't play with four fingers because it doesn't respond well. And lately it started to show some purple stripes on top. I don't know if there is Samsung technical service or where I could get a quality screen. I saw one on Amazon for $60 and another in a local store in my country for a similar price. Both have the characteristics of the cell phone (120hz, hdr10+, 2400x1080, etc.). I would appreciate your help.
