Pathetic Service from Virgin Active

For over 2 months I have been struggling with Virgin Active To link my new Discovery Vitality Membership with my Premier Membership of which I have been a Member of for a few years. Today, a debit order for R1,200 went off my account, double the Premier Membership debit order that have been going off my account and what was agreed with when I joined Vitality......Virgin Active increased my debit order without my knowledge or concent!!!+ Virgin Active, rectify my Membership and Active my Vitality Membership with my Premier Membership!!!!
