Extremely poor service from Virgin Active

I have never had such poor service before. All I wanted to do was cancel my gym membership but even that was to much to handle for Virgin actives administration department. I had to continuously call them after an amount substantially larger than my cancellation fee was debited from my account. I then had to argue across simple mathematical equations to prove they had incorrectly debited my account. My poor experience with Virgin active only grew after they then refunded a substantialy lower amount back to me days later and I was then told after having to phone them AGAIN that that was the amount that needed to be refunded. After arguing across simple mathematical sums AGAIN, I was told that it would need to be investigated and that I would receive a call an hour or two later. THIS WAS ON THE 09/04/2015 and an entire DAY later I have still not heard anything. You can be sure that I will NEVER REFER OR REJOIN VIRGIN ACTIVE EVER AGAIN...
