Annual increase after 2 months membership

I joined virgin active as a higher paying premier member in November 2015 . I have just received a annual increase I sent Virgin my thoughts on this on Facebook they tried to justify it but it's unacceptable in order to recieve a annual increase one would have to have been a member for a year not 2 MONTHS it's absolute slap in the face considering Im paying a higher fee to be a premier member as well I recieved no notification they **********ly debited the my account the higher amount and what's worse is that I held the conversation regarding increases when signing up in November I asked the question to the consultant and I was told that I did not have to worry about any annual increase until I had actually been a member for a FULL YEAR . If this is not addressed I think I will cancel the contract purely based on the fact that virgins ethics are poor taste and they forget they are not the only gym around
