virgin active membership and vitality

i'm a currently a member of virgin active with national membership because of my previous club southgate closed i'm enjoying the benefits of national but now i wanted vitality active and enjoy the benefits too but i need to have an qualifying product in order for me to have vitality which i did get life cover and discovery card but now since i have those i went to my gym to ask them to add vitality account on my membership i was informed i will have cancel my exisiting national membership for new vitality membership which for me doesnt make sense i will end up paying more and taking new membership while im on month to month and new membership will be 12 months and if i have to take national vitality the premium will be high including lifecover and vitality its not saving the information is not complete its misleading now i have to cancel all the products that i have signed up for and keep my national membership i feel ****med .
