My phone was blocked, because I at mobilcom debitel debts in the amount of about EUR 700.-, as I have apparently called the following telephone number: 09005770166. I did not call this phone number with my mobile phone. So I searched this number on the Internet and found that in the use of video games for the mobile phone somehow this number was chosen. However, when I choose this number from my fixed line connection, I reach nobody and I get an announcement that this number is not reachable. I assume that the calls registered in my mobile phone were used to play with one of the following games I have on my phone (Iphone) and received through the App Store: Smashy Road 2, Tom Gold Run, Slither.io, CrTeossy Road and Toilet time.
