Bed experience ever

I joined them 2021 they had a black Friday special which was R99 per month for 3 years so the contract ended last year November but to my surprise they deducted R200 and some odds in Jan and I reversed it coz I did not give them consent to take money from me and according to what I was told I was on a 36 month contract and it ended apparently when the contract ends they automatically put u on another contract without your consent what is worse the amount defers are they not supposed to first speak to me before taking an amount that I never discuss and agreed on with then what apsets me the most is to take to hand me over to a collection company as if I owe them something I paid all my premiums for the duration of the contract what else do they want from me they now going to mess with my credit record cause a collection company called Nimble called me this morning ZONE FITNESS PLEASE FIX THIS I DO NOT OWE U A CENT.
