Rewards program is appalling

Your Rewards program is appalling and your Chat box agents even worse. Last Friday, 1 Nov 2024 I unlocked 2 DStv Rewards Uber Eats vouchers (R50) each. I tried using them on the Uber Eats app and every time I get an error message to say I can't use this promo code. 5 Nov 2024 I reported the matter via chat box and I conversed with a Nangamso, she gave me a reference number and said I must check again after 24 hours. She insisted that I need to do this follow up via the chat box again and I asked why because they would have had my details but she was so rude and told me that was the only way to get feedback, I was shocked. Yesterday I followed up, via the said chat box, mind you, you talk to the machine you have to enter your details, you chat to an agent you have to enter your details again, I mean, that's a hideous process - I was told to follow up after 4 hours. I let 4 hours pass and only followed up today in the afternoon, now this agent today asked me to start my story from scratch, regardless of the reference number I gave her. Do better guys! Don't mislead us with rewards that are not valid and please employ agents with good customer service skills!
