Leaving out information

It's seem the staff at Virgin Active Lonehill will do anything to hit the numbers, including leaving out important information like when my first debit order will come off my account. This after asking the sales assistant in this case Karabo how this promotion they were running works multiple times. Not once did he mention that my debit order would come off a week later.all I needed to do was pay for my card he said and I would be going to gym for free.i asked what would happen should I not attend the gym 24times,would I still get the cash back? His response was you will pay the standard gym fee. No mention of actually your first debit will go off next week. The promotion was poorly explained and information was misrepresented . After calling and speaking to the sales manager all I got was we apologize!and my money!? I asked for an email detailing how this will all work and it's a week later no response! Who cares right? I am very disappointed. I repeatedly asked what was the catch and I was assured all is in order and I would make my first payment in August. I feel ****** and disappointed that I was not provided with the correct information...so much for honesty and integrity
