Unhelpful and Arrogant Assistance

I phone the call centre after being told I was in arrears at the gym and got such arrogant assistance from Mogsien Johnson who made it sound like I was in error for my account. I have been training the whole of last year and this year, and I have even changed gym locations, only to be told my account is in arrears for April, May and June of LAST YEAR??? I asked how can this be, because debit orders went off every month, I received no calls about being in arrears and have trained at multiple Virgin actives. Another consultant called me who also kept insisting that I must pay, except I don't know what I am paying for??? From April last year? They would have stopped me at the gym door, when your account is in arrears they don't let you in, I have spoken to consultants who moved my membership and there was no mention of arrears. In all my time ay Virgin active I have never gone through the type of service i received today.
