False info supp**** with contract

Dec 2013, after 2 gents did marketing at my employer with promise of a backpack if I join, because I stay in Sunninghill, I decided to go to Sunninghill branch to support the local guys in my area. The only info I was given is R239-60 for a family if I am a member of the Liberty rewards program which I paid R213-00 with no conditions mentioned. Up to today, I never received a copy of the agreement from Virgin active nor the backpack from Sunninghill (they did not have backpacks, but ivo the good deal, I was happy not to receive the backpack) Then Virgin active changed the conditions one sidedly to pay Virgin Active R1198 and Liberty to reimburse me with R958-40. This happened for a couple of months and then the reimbur*****t stop. In view of this false pretences the package was marketed and sold to me, the one sided change in the conditions make this contract ******* and null and void- I stopped my Debit order with effect 1 July 2015 as a result of this.
