Not giving coupon credit

<p>I got an sms from my bank for a promotion they are running with Uber. I was given a promotion code LIVEBETTER with which I am supposed to get R50 off my first 3 trips using my capitec card to pay for the trips before the end of January. First trip my son took, it worked very well, no issues we got the discount paying with my card. I then linked my son to my account as family (still the same Capitec card as payment method), then for the second trip he took, we didn't get the R50 discount. I have been sending messages for the last 2 days to get my R50 credit, but first got told that a different method of payment was used than the first trip. I then resorted in sending screenshots of my bank proving that it was still payment with my capitec card (which pathetic Uber couldn't even check on their side, I had to prove it!!!). Now even after proving that I paid using my Capitec card, they are ignoring me and not responding to any of my messages under the Help section of the app. This is pathetic!!! How can you offer a coupon with credit and then refuse to give the credit?????? Even after I PROVED to them the Capitec card was used!!!!</p>
