Unfair deductions on termination of my contract and poor services

I requested to terminate my contract on the 7 April 2019 - without any costs as I joined on the 7 April 2018. Virgin Active is refusing and saying my original date of joining was in August 2018 and the consulted communicated this with me (which is not true). I have informed them on numerous occasions that their admin made a lot of mistakes, but this is being ignored and I am being penalized for this. I can not be held accountable for something that is not my mistake and was never communicated. I WILL NOTE PAY 40% of terminating the contract, as my joining date was 7/4/2018. I want this to be dealt with and it should not affect me or my pocket. I was also informed that I will be called by a someone at Rooihuiskraal to resolve this and no one ever called (this shows how poor the customer services is) - but I do not care; I just want my membership to be terminated with no extra costs on 7/April/2019. Last year, I also had to complain after not being assisted for over 5month by the very same consultant Zuma on over payment due to the mistake that he made. Virgin Active is being unprofessional and unfair - I want my contract to be terminated on the 7 April 2019 - pro-rata deductions must be made for the 1-7 April 2019 and nothing else. Anything extra deducted must be returned.

I am a customer and can not be blamed for numerous mistakes that were made by the consultant.

My complain reference number at Virgin Active is: ********** 611 [Case: qB6flC, Ticket: TxVdmE].

Hope this will be dealt with professionally and fairly.
