How much did your Virgin Active fees increase this year?

I'm quite stunned with how much my fees are going up; for the last year I've been paying R240 a month for single club access (Milpark, JHB - which is tiny), I'm on vitality and have been going to that gym since I was a student (so for around 7 years). I got an email on the 29th of November saying my fees are going up to R345; an almost 44% increase. I know its still not that much relative to what I'd be paying without vitality - but I'm still blown away that they can just somma increase it by nearly 50%. Has this happened to anyone else this last year?
