Once again empty promises made by Vitality

It all started last year where I had to get a refund on my Virgin Active gym fees. Within the first month the cashback was not paid. After phoning, emailing and complaining for 3 weeks, I finally got my cashback. I was promised this would never happen again, but ofcourse it did.I had to contact them every single time just to get my money back. They then started adverting about how we could get 100% of our gym fees back in 2016, so early January 2016 I called and emailed to get more information on it. No one could assist me as they said it hasn't started yet. So even though it was 2016 already, I had to struggle to get info again. I was finally told that the gym booster will be activated on the 22nd of January and if I activate it before end of January that I will get my first cashback in February. February came and still no cashback, after numerous calls, emails etc. I was finally told that it will be paid out on 23 February. On 26 February still no cashback, so after enquiring once again, I was told he made a mistake and it will only pay back end of March. I referred this matter to the ombudsman who will investigate it.Its just sad that they keep breaking their promises.
