Questions: Technology & Internet

I bought an unlocked GSM (any carrier) iPhone X on eBay for $800 on Wednesday and it arrived yesterday and there’s nothing wrong with it except the very far right of the phone is unresponsive and I can’t use the letters p, l or m or send but I can scroll with it. I currently have t mobile pay as you go $40 a month unlimited phone plan. I took it to the Apple store and they said it was purchased on November 27th 2017 and it’s out of warranty. They did a complete diagnostic test on the phone and found nothing wrong with it except the touch screen on the right isn’t responsive. They think it’s a pinched cable in the phone. The phone has no scratches or marks on it. It’s not water damaged. It looks like it wasn’t even used. Everything works except I can’t scroll or type from the far right screen. It holds a charge. Cameras work. I currently have an iPhone 7. Nothing wrong with that phone just wanted an upgrade. Apple technicians said I should probably contact the seller and see if I can get a refund and send it back because it’s not cool that they ripped me off like that and they wouldn’t advise me to pay an additional $300 because they shouldn’t have sold me the phone like that but it’s up to me because everything else in the phone works perfectly and the phone isn’t damaged except a defective right side of the touch screen. But they personally wouldn’t pay more and would get a refund if they could. I contacted the seller around 3 hours ago and still no response but it says returns not accepted. The seller has a 94% rating and all their listings are iPhones of all sorts.

I think social media comments shouldn't be protected by free speech because even though It should support the first amendment, and this gives us the right to express our opinions without getting penalized, people should be held accountable for what they say online, because it can be considered cyber bullying if its directly at someone. But when you think about it, our free speech online is already taken away to a certain extent because there are options online to report someone's opinion because its "offensive"

Red light is blinking slowly. Screen is off. I've been charging it off and on for 3 hours and it still won't turn on for even a split second. What should I do? Should I keep charging it? It cooled down now, luckily because it was hot!

Last thing I remember; some girl was messaging me on Messenger and it just started blinking red. The phone screen went black. It's nothing out of the ordinary and this happened once before. It also overheated after being on the charger for an hour or so. I took it off and put it back on the charger a half hour later. I've tried pretty much every charger in my house on top of it!

I don't know why I'm so worried to have to write this question but I'm scared. I need my phone for tomorrow! I don't even have everyone's phone number memorized. Help! I'm trying not to have a panic attack?
