Uber duplicate payment **** on listed cards on the app

I had used uber on the 21 August for a short trip that cost R30 which I had used my card details to make a payment , shortly after I received and email with normal payment information and ride information as usual. A day goes by and I received a notification from uber saying I didn’t pay so I made another payment even though it was showing on my banking app that it was paid , today I received another notification from uber for the same trip I took on the 21st stating the new amount for the trip is now R530 , I’ve tried disputing the amount and they have tried numerous times to debit my account with out my permission. I’ve reached out to the support team but it seems like they are not trained enough to understand simple English and my issue at hand. I use uber quite daily as a means of transportation and is highly disappointed with this issue that is yet to be resolved (which might be highly unlikely since the support team is not understanding my complain) Uber is now turned into a company that ****s their customer into paying unreasonable prices for trips they had already paid for ….
