Blood Suckers, bad customer service, empty promise in thr name of money/contract!

I joined virgin active in October, i was told there and there that im on promotion, that i will get November and December for free, and i paid on the day of signing, but to my surprise they deducted on the end of November, and the unfortunate part was that i didnt have money in my bank account, and they kept on calling and i have been telling them that im supposed to be on promotion as per our agreement on the day, this not only affected my lifestyle, but credit record too, at the sametime i could go in as the day that we agreed that they will be debiting my account was incorrect, leading my account to be blocked, this didnt not end there.. But they called again, trying to recover that amount on the 28 November 2022, they were now saying, that meant they should debit the first installment, but i explained thats not what i was told, i then told the guy that i wish to terminate as this was affecting my credit record, he then ins3on calculating my cancellation fee which was amounting to R2500, but i was puzzled, but how so.. they are blood suckers, they just want to chow our hard earned money, not only that, today again just now now, they tried to debit again, it didnt go through, wrong date again, im getting paid on the 15th every month. I no longer wish to continue with this contract!!! At the sametime i dont understand why pay the R2500 again when they messed with my credit record with their lies, and wrong debit dates! They are blood suckers! I wish they could terminate my contract with immediate effect! I joined with the virgin active in Bloemfontein, the Fichardtpark venue!
