Being overcharged for Virgin Active

Hi there,<br> <br> It has come to my attention that I am being charged the wrong rate for my Virgin Active membership. <br> <br> Previously, I was a dependent on discovery vitality, but as of November 2015, I am a principal member. <br> <br> I contacted Vitality to enquire about the problem and I was told to contact Virgin Active directly. <br> <br> I did so, and they informed that on their system I am still listed as a dependent. <br> <br> I require that Vitality inform Virgin of my status change immediately (before I am charged in the next month), and that I am issued a credit for the full amount that I have been overcharged since I became the principal member of my account since November 2015. <br> <br> I expect a response urgently, as this is not a matter of customer service, but erroneous charges, which are serious in nature. <br> <br> My membership number is: ***<br> <br> Thank you,<br> <br> Gavin Joffe<br> <br> Id number: ***
