Gamestop won't let me return an iPhone?

A few days ago I purchased an iPhone 3gs from my local GameStop. The cashier told me I would be able to return it within 7 days if I decided to bring it back.

In the meantime I was able to get my hands on a better phone so I tried to take the phone back to GameStop. I still had everything they gave me… Box, accessories, phone, receipt, etc. Everything.

They turned on the phone and checked the serial number and told me I could not return it because the SN did not match the one on the box/receipt. BUT this was the SAME box in which they sold the phone to me!

Did the cashier who sold me the phone perhaps put the phone in the wrong box with a different SN? What can I do?

Should i delete all social media accounts?

So most of you know that I have been getting really bad comments on how I look and to be honest I'm 13 and it is causing me anxiety, daddys booked a holiday to get away from it all so that's good I guess, but the comments will still be there on my iphone when I get back so I dunno weather I should delete all social media sites,

opinions please

IPhone 3 randomly going to voice control and songs?

Okay, so It's 8:00 AM for me and I feel mad. At 3:30 I woke up by a sound and opening my eyes, my phone next to me was playing #Selfie (My brother downloaded it for me) I got freaked out and just muted it. Then, at 7:00 AM I woke up AGAIN! Just this time voice control was talking, I put cancel and shoved my face in my pillow. I can't sleep now and I'm exhausted.

To go to voice control, or to put a downloaded song you need to press the home button at the bottom of the phone. I didn't press that button and they just appeared. My phone is acting weird, help.

Can I upgrade my Mac in any way?

I have a 2011 Mac and I was wondering if I could take it to an apple store or somewhere to get a new one for less. I know you can do this with iPods, iPhones, etc. But I have never heard about it for Mac. I really want the 2013 Mac. Answer soon!

I accidentally put my iphone on a wet surface?

So what happened was, I put my iphone on the table without knowing it was wet. When I figured out it was wet, it was already more than 15 minutes since I put in on the table. I was playing music that time. I immediately wiped my iphone with a towel but in the middle of wiping it suddenly the speakers sounded like it was covered. I'm not sure if this is because i accidentally pressed something or because of the water, so please help.
And if it is because of the water, can you tell me how to return it back to normal without going to a repair shop? I'm afraid my mom would kill me ;-;

Inside glass panel on my iPhone 4 smashed?

I've had my iPhone 4 since Christmas and I have it in my pocket all the time and it has never smashed! I have a plastic case on it as well. Yesterday I got it out of my pocket and the inside panel on the back had smashed but not the case or outer panel on the back! So it's not sharp to run your finger over, but I don't understand how this could've happened? As the case and outer panel didn't smash, but the inner one did? Any ideas on how this might've happened and how much it will cost to repair?
