UBER DISAPPOINTED

Speaking to Jess now from UBER EATS, and my gosh, it sounds like I am speaking to a Chinese, Korean lady. I have to repeat myself over and over, and then this woman tells me the postal code needs to be 6 characters???? PLEASE TELL ME WHERE IN S.A. DO WE HAVE 6 CHARACTERS AS A POSTAL CODE?????? It's not a wonder people are complaining about UBER EATS. Jess put me through to Mary, Mary, CHinese, Korean, tells me after 15 minutes wasted of my airtime, and my time, I need to log the complaint on the UBER EATS APP. I asked her where to go, she cannot even explain that to me????
