Lack of response to problems !!!!

I wish I could give 0 stars. I am actually shocked at how pathetic the service was. We agreed on a set amount , and the first 3 months according to our contract we should only pay half the price. Instead Virgin active billed us the full amount. I was furious and immediately contacted them and told them abiut said problem. They acknowledged it and said a solution will be given. By the end of June no responses have been given and I contacted them again. I was told the problem would be fixed by the time the next debit order will occur. The problem however was still not fixed as I was billed the full amount again. I find it very shocking that they made the exact same mistake again after being informed of their mistake and made no effort to fix this!!!
