Bad customer service

I am even tired typing after the dissect, I did a chat with Tsholofelo Rammule advising that I did wheel spin reward and got a box office movie on you, I claimed it on the 18th October and was advised it will be credited in 7days but it's not so chatting to the agent she says I have to claim voucher advised it's already done I even have email stating than she says I have to claim it, I asked to speak to a sup because she won't listen, she just said she would love to help and ended the chat, my time data and having to chat to someone else I want to lay a complaint against this agent
