Virgin Active sharing personal information without consent!!!

Virgin Active accounts department neglected to correspond correctly with upon cancellation of a previous contract. Wanting to rejoin now, the sales staff at Paarl branch notified me of an apparent outstanding amount. To top this, my banking details they have, and which I confirmed on my new application form, changed itself to a non existing bank account on their system. Apart from all the above, they went ahead and phoned my emergency contact and shared my personal account information with that person, without even attempting to contact me personally. This sharing of my personal information without my consent is unacceptable, and shall be reported to POPI. I have requested the agent at Paarl as well as the branch manager to advise me on the above with a zero response.
