Bad service

I joined this med insurance this year Jan thinking it will easy the medical aid pressure. I was told it covers GP visits and I top up for hospital cover as well. I got sick recently and went to clicks was told the Flexiplus does mot allow to pay for medication as well as the clicks clinic I had to use my last cent to make the payment. I told them and they said they will cancel and refund me back within 24 hours this was on the 27th of Marxh till today I have not received my 3 months refund and they do not respond back to emails.
