Poor Service, I want my money back!

On the 18th of October 2020 I bought 2 Supabets vouchers from Blu for R100.00 and when I tried to redeem the vouchers I was getting 'Unsuccessful Redeem, Voucher not Found' error. I then sent a WhatsApp message for assistance on the 19th after trying to resolve the issue for several attempts. The agent that was assisting did not given their name yet responded and asked for my cell number and username after giving the details I was not told what the problem was but was told that I should expect a call and the chat was closed. 3 days later I still have not hear from anyone from Supabets and I am still waiting.
