Vodafone — Deduction of money from my account without my knowledge/ permission and without any service.

Recently few amount of money has been deducted from my account without my knowledge and permission. And displays as " thankyou for choosing to access contakt gaming services ." And then the next" Thankyou for choosing access to Telsync games " and then today it was " thankyou for choosing access to games and videos " . I mean what is going on scamming all the people for nothing. What the hell is going with this companies. Please fix this issue or its time to change the telephone service.
