I wanted to test Habio, so I thought I bought a two-week trial period for €9.99. Suddenly my account was not only charged with that, but also for the workbook €29 - so I paid for two different things, but authorized what I remember only one, and four times more than expected. NOT using Habio anymore, felt cheated, and can not trust them. My card is important NOT to be used randomly! So deleted and BYE.
