Poor Customer Service

I have a discovery vitality and a health policy , i was asked to pay an amount in cash for arrears and my instalment ,after having done that , Discovery debited the same amount from my account on month end.

i called and asked for a refund and after being transferred numerous times, i was finally transferred to the health devision where i was promised a refund , it is the 14th today and still no refund, also no feedback from the consultant who promised to do so.
