MEDICAL AID NR ***0- No Feedback!! PLEASE HELP!!

After numerous emails to all email addresses that can be found for SizweHosmed - I have still not received any feedback / phone call with regards to money that is owed to me. Re : MEDICAL AID NR ***0 MAIN MEMBER CJ WOLMARANS - there was a duplicated amount debited from my account. I have forwarded proof of payment and bank account statement to Mr Denis Negondeni - who has requested it, and have sent 2 emails afterwards requesting feedback and I'm still awaiting any form of feedback from SizweHosmed & Denis. No Phone call, no email. This is VERY appalling service - Definite lack of customer service and I would not recommend anyone to join your medical aid. This is *****ing money from your loyal customers! Please CAN SOMEONE assist me to resolve this issue swiftly?
