Wrong info provided! Now I'm left with the mess!

My partner and I went to Virgin Active Comaro View on Sat 25 July '15 to get her to join VA at my expense. So we went to see a consultant at the gym. I explained that I would like to get a new membership for my partner, and that it should allow access to any gym in the country. First he gave me the option to go on the Premium Select package but this was not suitable. He then offered the Premium package and explained that the rates would be a once off payment of R1300 to join and then it will be R189pm for my partner and R370pm for me, until I go more often. We agreed and got the paper work sorted. I was not offered anything like a bag or even a water bottle for the R1300 I just paid to join a new member on the TOP package btw, but okay, I guess we dont get anything for the huge amount of monies just paid, not even a welcome... Now after the first payment has gone off for our monthly gym fees I unfortunately learnt that her gymming fees arent only R189pm but R370pm and that the wrong info was provided. No apologies were made, in fact it seems VA just doesnt care. So now I am stuck paying R370pm and quite frankly I should just shutup about it! Thanks for nothing VA. Disappointed!!!!
