Changing my Premium without Notice

I have been with Virgin active for a good number of years.

I however got no email or correspondence with regards to my monthly cost that is going up due to me missing 1 month of not going to gym. I want someone to please contact me with regards to this because this is not how I do business or else I can arrange to take my business else where.

This is unacceptable to get an email from discovery health last night stating that in a week and a half's time i will be paying more. No amount as to how much more nothing just virgin will be debiting your account of up to 50%.
