Cancel and reinstate Multiply shocker!

My sister & I cancelled our Multiply July 2015.Today I phone to reinstate our membership as we were told that we could at any time.The Consultant who took our call today asked us to pay back arrears for cancelled period or wait to start after 3month cancellation period expired.This information is not on any of the momentum website. All calls are recorded so Momentum must go back to the day of cancellation and provide details as to why we were not advised about this regulations. What benefit is it to Multiply if the company withholds this information.It affects us so why should we not know about it. Another shocker is that we were at Virgin active and we would like to go back but according to Momentum we have to pay another R240 for an assessment that we have done less than 3 months ago to qualify for the 80% discount. The Ingwe medical aid is perfect for us students but Multiply is a *******. We are students paying fees and travel for studies where do we have this kind of cash to waste or pay. Momentum must reinstate our Multiply membership with charge as we were not advised. It is sheer disrespect to us Students if the Consultants don't feel that we deserve to be advis
