UberEats Discount Voucher *****

On 9 July I ordered food while using a promotional voucher code EATSZA703HA. I clicked on the email link and app**** the discount of R70. During the order process the discount was app**** and showed that it was deducted from the total price. After I paid I noticed that UberEats charged me the full amount. I complained via their app and via email, but they refused to address the issue. They think that if they ignore you long enough then you'll go away and just let them ***** your money. I guess they will only react once I start splashing this all over social media
