Delay in cancelling vitality membership

I called at the end of Nov 2015 to cancel my Discovery Vitality Membership. <br> Spoke to Trishelle ref nr. ***. Was told that I would be contacted within 5 working days to confirm the cancellation. <br> This did not happen so I called the call centre on 9/12/2015 and spoke to Zane ref nr ***. Was assured that this would be sorted out asap. <br> <br> I am still waiting and it has been rather tedious trying to call again- extremely long hold times. I just want my Vitality membership cancelled immediately!<br> <div><br></div><div><em>(Supplier name changed from Discovery Vitality &amp
