Planetfitness Trash contracts and admin

I joined Planetfitness Parklands branch in January.I was recruited by a guy called Super M and he was kind to advise me that they can offer me contract with my husband since he had Discovery and we would get a better deal with vitality.The contract was for 24 months.In July i had 3 debit orders that were from Planetfitness and i went to their branch after the call centre said one amount belonged to my husband.And to my understanding i have been paying for both of us since we started.They failed to explain and i visited the branch and I spoke to Megan who was new.She advised me that my conversion to Vitality mbership was never done.However my husbands was done.This error has caused me to be paying more than what i am supposed to be paying since inception.They dont want to fix the error on their side as i did infact sign the conversion.They now want me to pay for the conversion.I did the vitality contract together with my husband at the same time. It is not through any fault of my own that this was not processed by their team. The failures of your staff should not cause any financial burden to me. In all of this back and forth i have to keep on calling the head office and the Parklands branch and Megans promises to call back pr resolve the issue fail.I was also promised a call by manager to this day.The head office is quick to close the matter without even calling nor emailing me for feedback.I am so disgusted by their service. I Will never ever reger anyone to this gym.
