No customer service, just stress

I wish I could give no stars. I've been moved from Spectramed to Health Squared but received ZERO communication that this would happen. Apart from that, you increased my premium by almost 70%, yes that's right?! and this also without my knowledge or approval. This is *****, do you know that? I have been trying to sort this out for over a month now. When I phone your offices I have to hold on for over half an hour just to be told my email will get a response in 7 working days. Are you kidding me? Your service is horrible. On 21 Jan 2019 I get an email from a company called ZFS Financial Solutions and the Managing Director. She said "We are a Financial Services Provider for Healthsquared Medical Aid. They have directed your query to me regarding your new option." After 13 or so emails, I still have no answer. After their ********** debit order, 2 of my debits can't go off and I receive penalties because of this. I'm just so fed up, how can a medical scheme look after your well being if they can't sort out their clients' complaint/issues? I honestly don't event expect you to reply.
