What a joke of a medical aid, they are more happy to take your money but they won't pay back when they need to

I dream of the day when momentum does not make it difficult for me to keep my membership with them.

Over a year ago I got my dad medical aid with Momentum, my dad was retrenched in 2014 and has not worked since then, he financially dependent on me. The medical aid that he's on is being paid by me, I manage everything as far as the medical aid is concerned. The money gets deducted from MY account. 03 January Momentum took R3200+ from my account instead of R620. I called them, they ask that I send mt bank statement which I did. They said it would take 3-5 days to get my money back. It's the 16th of January I have not received my money back. Your pathetic call center agents refuse to help me because I'm not the main member. I am told I need to get my dad to sign a consent form, which I am okay with except 1. It's my money 2. my dad stays in another province and I won't be seeing him for a long time. He doesn't have internet access where he is so what must I do now??? Excuse me but you don't seem to mind debiting my bank account every month even though I am not the member. This is pathetic, I want my money as in yesterday.
