Not honouring R1350 voucher agreement

I joined Virgin Active during the month of September because of the promotion where I would get a R1350 Adidas voucher for going to gym 24 times by 30 November. My voucher did not arrive on time so I called in and was told I had only been 23 times as there was 1 visit that did not count. I was aware of the 1 visit per day rule but had forgotten about going twice on one of the days. As the MyVirginActive app was telling me I had been 24 times I was satisfied that I would get my voucher. I asked how I was meant to confirm the visits which did not count and they said I could log on to the website. I have just logged on to the web site and it states the following about my visits:<br> <br> \Total visits: 24 (1 not counted)"<br> <br> The app says this:<br> <br> \""Total visits 24\""<br> <br> I find this to be inconsistent and misleading. There is obviously a reason that the web site tells clients which visits don't count. Yet this has been left out of the app. I'm now being told I will not get my R1350 voucher because I re**** on Virgin Active's own app to give me correct information about my visits. How is that fair? If it weren't for this voucher"
