One of the worst companies out there, I think they are doing illegal stuff but for some reason nobody cares to investigate them. Had to cancel my contract, submitted all the documents as described in their page, and I get the answer after a few months that I still need to hand-write a termination letter even though I submitted the form they have created explicitly for this purpose. The reason why they answer a few months later is simply to keep charging you as long as they possibly could, and the funny part is that they will notify you about the hand-written termination letter one day after the pay day, so, you still get another month to be charged. Never using their service in my life again. Another lost customer for 20-30EUR extra they could squeeze in.
