Billing

I signed a 12 month contract from 30/8/2013 until 30/8/2014. I have not signed a new contract or used your facility after this time yet debit orders were taken continuesly up to a few months ago when I was forced to cancel the debit order as I do not see why I have to keep on paying for something I am not liable to pay or that I do not even use. I do not understand this way of doing business. Now I am being harassed with legal action!? I do not want any part of Virgin Active any longer and wish to finalise this matter once and for all.
