Pathetic service, don't keep their promise of a refund when they're in the wrong

I recently posted how they took more than a month to respond to a simple query where they *****ulently deducted a higher premium from my account. Finally someone contacted me and made every excuse under the sun including a technical glitch that by the way they had not picked up or fixed for over a month. I was promised a refund and it would take 2 to 5 days. It is now day 9. Gatvol of their pathetic service and false promises. How hard is it to process a simple refund? Time to look for a new medical aid
