Zone Fitness is making me go broke!

I am so frustrated and disappointed. I have posted on this site to complain about multiple debit orders going through my account. I have tried to freeze mine and my two daughters membership as the branch is under renovations. I recently spoke to a lady called Rebecca, Zone fitness Rondebosch. She assured me that she froze my accounts. That is after trying to get this frozen before. Last month clocked up 1900 on bank charges (my bank charges 150 for every return) previous month 1200 and the month before 900. When the debit orders for myself and my daughters did not go through they attempted to debit an additional three times. So basically once a week. My bank can verify this. I am desperate. I see now again, an amount has gone off for the three accounts. I am now going to seek legal advice and this is going onto Hello Peter.
