I am sorry but new devices do not behave this way. to factory reset the device, its in the software menu in the settings page. scroll down to security i think (going from memory) and you have an option to factory reset.
however, I would suggest you take it back to the shop and get a new device, assuming you still have a grace period and get you money back and go elsewhere.
given their reluctance to help you, you should just ask your money back. its clear to me this phone is not brand new sealed when you got it and it sounds like a bad rom is on the device, or some wonky virus or its has some internal damage.
bottom line; if the phone does not behave properly after a factory reset, its defective period and should be exchanged. there is nothing people over the internet can do to help you as we will be just going down a rabbit hole into the abyss
and without having the device in hand to test, it could be anything causing the problems you are experiencing.
I know it's not rooted because I downloaded an app to test. I've had many dealings with the shop in question. When you take a sealed device in to them they give you money for it, cash or store credit. All sealed devices, discs etc are opened by them, devices are tested. A Grade means it was brand new when it went into their store before they tested it. I only buy A grade devices from them, never had a problem before and have bought and sold many items to them. So no, you're right when I bought it, it wasn't sealed because they have to test every device they sell.
It comes with a 12 month warranty, I have been in contact with them, they've told me to go in store and if they can see the problem replicated they will exchange the device, pretty standard for any store really, you gave to show them it's faulty.
Battery is draining pretty quickly so should be able to replicate one problem to them when we go in to the store tomorrow.
