MBD and Virgin active are disgusting and not helping

Yet another review on MBD!!! So I was approached to take a contract out with virgin active in 2019 I was told that the first 2 months is free which sounded amazing so I signed my brother up and myself. We signed up in November, then December we went a few times, and then in January if I'm not mistaken they debited my account in the beginning of the month so I know that I'm a single mother first of all and I have to keep funds for school clothes for 2 kids and stationery etc, they went into my ACC on a date I did not agree to and drew funds. I called the guy that signed me up, unfortunately I can't remember his name, then he says that the membership is paid in advance for the month so in the month of January I will pay twice so I said no I can't do that because I have kids to send to school, why wasn't I told about this when I was signed up because if he did I would of never joined. He went on to say that i need to speak to management the normal process which I done. I told them to please cancel it immediately because I was mislead into taking this contract and I don't feel that's right because they took advantage of me and held back information so that I would sign up with them. I contacted management, spoke to them and then they said that I can pay a certain amount which I did not agree to because this was not my fault and was the guy who signed me ups fault. I sent emails upon emails, the very last email was me asking for feedback which I didn't get to date. All of a sudden MBD calls me to pay I explained to the consultant he said ok I must send an email which I done, I then received an email with a response from virgin active that I need to pay that amount. Now MBD are not even trying to assist me because I have every single email, every single date, every single correspondence but they still are demanding payment and I refuse to pay because they mislead me into signing up for this contract. MBD really has useless employees there and are really of no help. They messed up with my mum's account now they starting with me.
