Empty promises and no assistance

I recently joined Virgin Active with many promises and am very disappointed. When I joined I was told my first debit order would be deducted on the 31st of August only for the debit order to go off on the 1st of August, my sales representative has done nothing about this even after numerous conversations regarding this. The app which I have downloaded took 3 downloads and resets before it worked. It now works but none of the reward options are working. I have spoken to staff numerous times and the only answers I get are we have logged a call lets try next week. I signed up with all these promises and receive none of them. I am very disappointed as I am not a discovery member, I pay full price and really expected more
