Early deficits!

After about a year in use I send (if the Intenso service the ever permitting) the unit now returns. Especially the Amazon app crashes constantly from and does what she wants, the tablet displays the pages to which it just feels like and some do not. For a week, a white pixel line runs across the display ... well reichts. The online complaint form from Intenso is not practical because of the security code to be entered is not recognized (such a nonsense ...), a call to the support would dearly: 1,99Euro / Minute, fixed line goes with me not, but also what cost : 0900 number, rip off. Now I once wrote an email, in my experience, the / answered read almost never of companies. Do you notice: I'm just so pissed ...
