Refund

I bought an HD decoder online on the 18th of October. After i received it i changed my mind. I called Multichoice customer service, i was advices that i needed to take it back to my nearest multichoice customer service which is in Randburg. I was assisted by Tebatso. She advised that they will escalate for a refund. RAM couriers contacted me on the 4th of November to say they will come collected the decoder. It was then collected on the 6th of November. I waited to be contacted regarding my refund and no one did until i decided to call and do a follow up. I was told i need to send bank statement as proof and proof of purchase. Which i did and i was told i need to go to the customer centre again. I was assisted by Lara on the 26th of November who said she will contact me to give me feedback. I emailed her to follow up she didnt respond to date. I’m not happy about the fact that no one is calling me to update me and i havent received my refund till this day
