Double debited

My account has been double debited every month, when I raised a query I was told 2 months ago that it would be sorted and that I should continue as usual. Every time I go into the gym I am treated like a ******** that hasn't paid their account, I need to give the same story every day, the people at reception know the situation but still make me go on explaining the situation, not one of them have been helpful to me. I asked someone last week for a contact details for someone I can call to sort this out as the guy we have been communicating with was not helpful (Nolan), they took my number down instead but I have still not been contacted even a week later.
