Charged unfairly and no refund to date

In the middle of 07/2015 I had cancelled my Medical aid and hence my vitality also got cancelled which resulted in a sudden and drastic increase in my gym fees. <br> <br> I wasn't told by anyone at Virgin active that this would happen as I had paid a R2500 registration fee for the use of Vitality and then I would pay a reduced fee of R184 for me and my partner. I was told that it was a 12 month contract and even if I cancel the contract I would only pay a small percentage of the the outstanding amount agreed. AT NO TIME WAS IT STATED THAT MY PREMIUM WOULD INCREASE IF I HAD TERMINATED MY POLICY WITH DISCOVERY as I was under the impression that I had committed to a 12 month contract and thought it will remain the same for the duration of the agreement as I had paid a fair some just to register.<br> <br> On the 01/08/15 I was Debited R950 by Virgin Active to my amazement as there was no prior notice provided by Virgin active that they will now increase my premium. <br> <br> The best part is my Discovery premium was paid in advance and I was covered by Discovery health right until the 1st of August so even if this was virgin's policy they should of only debited R950 on the 01/09/2015.<br> <br> Very Disappointed?????
