I want to sue the company for using my documents without my concern

Yhoooo! SBK is*** they don’t offer what they promise to offer. When I was doing contract with them I told them I have a toddler they promised to look after the child because they say they is a caretaker at gym so I must not mind the child come the gym I was gyming with my child and after that they shouted me for not looking after my child while I was gym they I decided to leave the gym and not come back, it was a 12 months contract that started in June 2024… and I stop going to gym in November but I was still paying the gym because I didn’t cancel this April I went there to cancel the gym ask the money that I should pay to cancel the paid it signed and left three days down the line they called and said the cancellation failed I must pay R65 and 33 for cancellation to be done how because I paid R440 when I was there for cancellation why now and what for?… yoooo! Same day while I was still digesting that they called ask if I’m I interested in opening new membership from them telling me that my membership expired, do I want to renew. I went there to the office I find that I have three membership under my name and they left debit orders that makes R700 and something in my card .
