Tell HN: Uber decided to block all my payments and I'm stuck while traveling

Traveled to SA, Uber worked for the first day, then all payments started failing and it asks me to try another payment method. I tried 3 different methods, none work. There is no phone support for Uber, you have to hope someone answers you in time. Meanwhile, you can be stranded, it’s all the same to them. I guess they have some suspicion, if it ends up all being legit, it’s worth all the headaches and danger of walking around in SA at night.
