Disappointing!!!

I downloaded (thank God) 1 manga but the process was stalled and in the end I could not read anything! I wrote to Digital Publishing Store Support for help, but alas theyre no help either. And I quote, "Thank you for your inquiry. You are experiencing a COMMON technical error caused by poor wi-fi connection. When you are downloading a book, please be sure to have a strong internet connection. Please re-try downloading again. Apple will double charge you for the item you already own", and un-quote. Whats wrong with this picture? If its such a COMMON error, the DEVELOPERS of this app should already do something about it. Im not God, you know, I have no control of the wi-fi signal (whether to make it stong or not)! So are they telling me its my fault that I have a poor internet connection? Download again? Charge me double? I might as well buy the real tangible manga then. If the same thing happens again, what happens then? So in other words your just eating my hard earn money for NOTHING! Im not usually the ranting type but I feel cheated! UBER DISAPPOINTED people...UBER, UBER DISAPPOINTED!!!
