Will not refund me money

<p>I manually paid for my first vitality payment in January 2017, they then double debited me in February. Discovery claims they had not picked up that payment (even though I used the same reference as my medical aid contribution). I phone in where every time they say we have allocated your manual payment and the finance department will be in touch to refund you but this never happens. I escalated this to higher management and still no response. What will it take for discovery vitality to address this issue.</p>
