Refund

on Monday the 26th I made a online payment of R1256 to Wonga which was my last payment but due to finger error the payment was duplicated. I then contacted Wonga customer service to log a query for a refund. the consultant requested that I send through my last 7days transaction from my bank as well as both proof of payments which was sent ever since I never had any communication or what so ever from Wonga. I then decided to call Wonga customer Services to follow up everytime I call I will tell the agent my needs and she will then place my call for 10min till I hang up even today I dont know if my query has been logged or how long will it take for my money to be refunded.
