I applied a voucher. It showed up in my account. I went to pay. The pay screen showed the voucher applied. When I tried to pay it requires a credit card be entered. There is no way around it. Completely ridiculous. I naively believe they just want a card on file so I enter it. The payment screen still shows the voucher applied, phew. I go to click submit, and my card, not the voucher was charged. The voucher shows the full amount. I deleted my card from the platform, and don’t even care to use the voucher anymore. There is no such thing as customer service for this company it seems so I learned a lesson, they lose a customer for life. I only with the provider of the voucher could be refunded since uber so selfishly took both our money.
