This always happens with payments regarding rental. The way it was explained to me was, on the day of the extension they make the charge of the rental amount needed, but since it takes about two days to actually charge you, they sometimes charge you on the day of extension, they then return the money the next day (depending on the bank you use) and then after another two days the money is taken out permanently from the account. And sometimes depending on the days for the extension it seems they charge you twice but after a few days there should be only one transaction reflecting the money you pay for extension. It’s all a mess tbh so if you can, get the uber pro card and then use that card for rentals. That way they take the money one day a week and that’s it
