I am the person that will be helping you today.
First off, let's make sure it is not a simple fault. Please, press both the Home button (on the front of the iPad) and the Power button at the same time. Hold both the buttons down until the iPad resets. Once it does that, let go of both buttons immediately. When it comes back up, is it all working?
I will be standing by.
I am here. I am writing up the next set of instructions for you. Thank you.
It is a bit complicated, but that is the only option you have unless you recall the passcode. I will send up the refund request, which means I am not given any credit for my time.
I wish you well.
Thank you. The refund has been sent.
