Gift card and credit not working for six months

I have to write a review because they have some foreign support center who doesnt understand English handling the communications from within the app. I have a serious problem, I bought $100 worth of gift credit and have never been able to use it and its showing in the app that I AM using it but Uber doesnt use it. I select it as my payment type BEFORE my trip. And then Uber doesnt use it. 6 months now.

Tttttttttttttthhfgg about Uber, v3.245.3
