VIRGIN ACTIVE BOKSBURGH K90

I took my 19 year old daughter's membership off my debit order last year December. I made sure that I am just paying my membership for the first 2 months. Then this month I see that I am all of a sudden paying R1129 for membership fees. I phoned and queried and gets informed that my daughter upgraded her membership in March and that's why I am paying now R1129!!! I DID NOT SIGNED ANYWHERE OR GIVEN ANYBODY PERMISSION TO USE MY BANKING DETAILS!! This was done at the club Virgin Active Boksburg K90 itself - my daughter did not sign or given my banking details to any body!! THIS IS ***** you are not allowed to use somebodies banking details to increase member fees or add member fees without their permission. And when I complained via email and telephonically I got told that I am the account hold and will stay responsible.
