Virgin active breaching their own contracts!

I took out a gym membership for a period of 1 year, my contract was due to terminate on the 27 August 2015, In terms of the contract, Virgin active has a responsibility to notify when your contract is coming to an end and seek your permission to renew it failing which your contract will be automatically renewed on a month to month basis, nobody had contacted me with regard to this so I contacted my club who advised me that I will be liable for a cancellation charge, even though I had received no notification from them and their in breach of their own contract as well as the CPA, I appeal to everyone who has experienced this so that we can lodge a joint complaint to the Consumer Commission as this clearly violated the CPA.
