How to return an item on Ebay that said it wasn't returnable?

I bought an "iPhone 5" on Ebay with my mom's account, but the owner emailed her saying it was actually an iPhone 4. I just purchased it yesterday, but in the description it said that the owner doesn't accept returns. Since I haven't received it and it isn't as the title says, can I return it and get my mom's money back?

I've just contacted the seller and asked, but I'm so scared I can't return it! My mom has the Ebay money back guarantee…

Added (1). omg thank goodness! And no, i don't think the seller has shipped it yet.

Added (2). What do I click on to return it immediately? I would like to get my mom's money back and buy another phone As soon as possible because we're going on a trip soon.

Should i upgrade my iPhone 4S to iOS 8? - 1

I have an iPhone 4S, unlocked and I don't use this phone regularly. I have an overseas phone carrier SIM card installed with overseas phone number and I only use the phone for banking purposes, because my bank overseas sends password to access my account info to my overseas number only. They won't send it to US phone number. So I keep iPhone 4S for that purpose. I have been using the phone and overseas SIM card with no problem, when I'm not using the phone I just turn it off or put in Airplane mode.

Now i get a message about upgrading the iPhone 4S to iOS 8, do i need to do this? I'm affraid that if i do an update what if I can't use my overseas SIM card? Would that happen?

I accidentally got my iPhone 3G wet and now the power button doesn't work, how to fix?

As the question name says, I got my phone wet but not completely wet. The home button works and so does the screen. However, the power button isn't reacting and the volume buttons aren't very responsive. I can still shut down my phone by using the Assistive Touch features. The downside to that is that I can only turn on my phone by plugging in my charger which is not something I can always do. Can anyone help me with this?

How to delete All music off your iphone?

I got apple music which is freaking grand. I planned on wiping my old and unwanted music out of my phone and at first it worked so I was aokay with that. HOWEVER in order to use apple music you have to activate the cloud. Welp after I activated apple music again on my phone every FREAKING song is back. I have over 700 songs and the only way I can delete them is one by one. I can't believe that Apple would make something so simple so aggravating so I have to be missing something. If you know how to delete all the songs PERMANENTLY please tell me. I've tried EVERYTHING. And i'm a little ticked off.
