terrible service

I'm honestly losing my cool with Momentum! I've been waiting for 3 months for our new medical aid cards after they messed up. First we switched principal members, then they changed our member number and told us that we owe them 7k and my wife and i were not covered, then they said they will sort that out, then complained about the new cards and 3 months still waiting. Now I have submitted a claim and they are asking for my banking details like they don't debit my account every month. No man this is absolutely shocking... I really can't be with a company that is so *********** to be honest!
