Planet Fitness Lynnwood is robbing me

I was lured to sign a local membership contract by a consultant named Zelda from Planet Fitness Lynnwood, Pretoria when I thought I was signing for the off-peak option for R199. After I spoke to the branch's assistant manager who I have contacted almost everyday from the 5th of March 2018, I have not still heard from anyone from the branch. I noticed the incorrect contract agreement when higher debt orders amounts were going off my account. I contacted the head office and I was told that it was a branch-related matter and they cannot assist. I am still waiting for someone to assist me regarding this matter as I think I should block all payments going off from my account as I have not given consent that the amounts should be debited from my bank account,
