Virign Active have cancelled my contract once again

Virgin Active cancelled my contract in June/July due to underusage. I informed them I go to a private gym as well and had an operation. It was then reactivated. I was informed I need to visit the gym at least 39 times in the NEXT 12 MONTHS. It has been 2-3 months and I have received an email stating I can reactive my membership by 30th Sept for a reduced fee. This is clearly against what I was promised and is definitely not 12 months since reactivation.

I would like an explanation as to why this has happened? I have been a member since the inception of Virgin Active and I do not intend on paying a reactivation fee. I am highly upset about this and need this to be sorted out asap.

Thanks

Dani
