Virgin active increases

Annoyed as I just renewed my Virgin active contact a few months ago for another year at a reduced rate by Virgin active.. not only to find out that a few months down the line they increases the premium...that to me is Soo wrong on all levels.why give me a discount to renew for another year knowing that you going to increase it in a few months... allow that member to either complete that year at the discounted rate for the year which they lured you to continue for another year .or ask the member if they can't afford the new premium in the new year they can then cancel without penalties...this is not the first time they have done this to me
