Putrid service from Bonitas administered by Mwdscheme

I had switched to an individual status after resigning from my previous employer. Bonitas who is administered by Mwdscheme suspended my account as they said they didn't receive payment. I had sent numerous emails to them and everytime just got a message that said NOC enquiry closed. When I went to see them having to return to SA they said they couldn't find my transaction and monies paid. I went to the bank and git the proof. I also cancelled my membership and requested my money back. To date no one called to resolve this just an SMS that my membership will be cancelled end June. I want my money back, your service is putrid, you have no care about customer service. People should rather join another scheme. GIVE BACK MY MONEY.
