phone lasted only a year :( need help with replacing it

so unfortunately my htc one m8 i got just last year has become very inconvenient with me even tho I've treated my phone with such care. the top portion of the screen has now stopped working as well as a yellow coloration on the screen right by the volume rocker appeared. I don't know what to do, I recently visited a kiosk and told me my warranty just expired(i believe last day was 14th of may) and suggested customer support and see what they could to see if they could do something better for me. So went home and called, customer support told me that i should pay my remaining $-250 balance and upgrade instead. I don't really want to have to spend $250 at the moment and ontop of that spend extra for a new phone at the same time. I was wondering if there's anything else i should do or can do about my situation? I'll be willing to pay but I would prefer to not pay so much. It's really become a hassle for me not being able to see my notification or click anything around that area. Please help!
