NO action taken after 4 weeks of complaining

We received a quote from a Momentum broker, trying to move us over from Old Mutual. Promised it would be the same price (life Policy) with the benefits of Multiply for the purpose of getting gym fees down.. After moving over, too much money kept being debited by Momentum. So we set a specific amount aloud for debiting. So they Cut off my gym contract 1 January 2016. Claiming the amount excludes Multiply. After many many attempts to get the problem sorted, proving what we were quoted a specific price, and NO ONE taking action, i received a call with an apology and that the problem would be sorted latest the next morning and i have to pay for eye tests to sort this out.... NEVeR got the call!! I have emailed and messaged so many times, even my calls were not answered. WE are so stuck. And ready to go back to Old Mutual . Biggest mistake ever and has costed me more so far than my usual gym fee would have. WORST service ever.. I have now been out of gym for 4 weeks!!! What if we had an accident in that time while MOMENTUM takes forever to not sort anything out. How do you have brokers quoting incorrectly. We explained and proved multiple times. Never got my fitness test refund.
