Membership messed up by your consulltant and inadequate support provided in resolving this issue by your Call Centre and Northgate Club

I have been a member of Virgin Active through Vitality for more than 10 years. Beginning of September I joined a new medical aid which also uses Vitality, I was assured by Vitality that all my previous benefits including my gym membership would continue as is . On the 29th of September I went to the Northgate Virgin Active, and I was told there that I cannot get access to the club as my membership was only for the Braamfontein club (I have never been a member of Braamfontein, I have always had national membership). The sales consultant who is Philani told me I will need to rejoin, I told him it does not make senses for me to rejoin as I have been a member there for a long time, he told me that is the only way to fix my account. I asked him to ensure that my membership is national membership and he said he did that. The next time I went to the gym, I was told I only have club membership for Northgate and not national. I do not want Northgate membership as that gym is very far from my home, I need national membership. I have been trying to get this matter resolved for more than 2 weeks now and I have been sent to pillar to post by your call centre and Virgin Active Northgate. All of them keep on saying they will get back to me and they never do. I have made numerous calls to both and in the meantime this is still not resolved and I am not able to use the gym.
