Horrible, glitchy, can’t trust it

Half the stuff I enter just disappears; I enter the info, upload a picture, then the info. screen goes blank yet the info comes up when I double-click to edit it. However, despite saving it, I lose everything I just entered. I wasted over an hour filling stuff in then lost it all. Complete waste of my money and time, hopefully Apple will refund my money.
