Iphone 4s keeps deleting music?

Added (1). I have an Iphone 4s that has recently been updated to the new iOS 8.2 (the latest version). I had 180 songs before the update, and when i updated, i had 26.It gives me the option to go into itunes and download the songs i've purchased through iCloud, but it takes me a very long time to download some of them back (i can only have 80 now thanks to iOS 8. After i download them back, an hour or so later i go back into my music and i only have 39. How can i stop this from happening?

MacBook Air or iphone 6 plus?

So I don't have a phone and am planning to get the iphone 6 plus, but now I'm debating wether to get a expensive phone I don't desperately need or a MacBook which will help me with school work etc.

The price for both is approximately the same

With the iphone I can make calls, text, listen to music etc. Whereas as the MacBook I can do homework and browse the web that's pretty much it.

(I'm 14)

Bought an item on eBay, seller asked me to send the payment directly to his PayPal and I did?

So I bought an iPhone 5s on eBay for $300 bucks. I paid normally, later the buyer asked me if he refunded my money would I send it to his PayPal email directly(bypassing eBay seller fees). I said yes, and he refunded it. And I sent the $300 straight to his bank account. He told me that he still had the seller fees and he wanted to cancel the purchase. He already printed the shipping label on the first day I paid though, If he doesn't send the item is there any way I can get my money back?

How much would it cost to fix my iphone? - 1

I was out with friends yesterday and I went to open my phone and it didn't turn on. A few minutes before it was on 70% battery. But I figured it died because my phone has always been weird with its battery. So I went inside to charge it and it wouldn't turn on. I noticed the lock button felt stuck but if that's the problem why is it not turning on from the charger? I get home and plug my phone into a computer and the phone (after a long period of charging) finally turns on. Everything seemed to be working and when I pressed the lock button it worked even tho it felt stuck. I just woke up this morning and noticed the volume buttons don't work and the silent/ringer switch no matter what will say what you switched it to but the phone is stuck on vibrate. Is there a way to fix everything and how much will it cost?
