Savings Refund Bonitas

I am a Bonitas member and I changed my options from Bon Classic to Standard Plus option the Bonn Classic option has a savings option and I have money in my savings that Bonitas need to pay me back, I send a mail asking when will I get the money back in my savings. I have changed the option as I am a pensioner and they increased the medical aid with 10.7 percent and the premium is too high for me to pay. The money in the savings they informed me I will only get paid in 4-5 months time. I feel really I must wait nearly a half a year to get my money back. I just feel this is unacceptable it is my money. It is now 2 months that I am waiting and I really need the money.
