Cancel membership nightmare

After not getting in touch with a call center agent I informed virgin active via e-mail that I am canceling my membership. No acknowledgement of mail, still no answer at the call center, 2 weeks later, I mail again and cancel my debit order. A further 2 weeks later, I send another mail. This time I get a response that my request will be backdated. Today, almost 3 months later another debit order goes off. I finally get hold of a call center agent who informs me the contract was never cancelled, then drops the line. Beyond pathetic...
