Ubereats bunch of *******

Accidentally selected to pay cash, couldn't cancel as the app didn't allow. Ubereats has no number to call for queries. Ended up calling the driver and he said not to worry, he will cancel it. They kept trying to take the money from my savings account that I use for for ubereats and other small things, I just transfer what I need when I do. Send emails asking them to stop, no response. Other day wanted to order food, oh my husband's ACC details, ended up not getting anything and boom, Ubereats *****s the old money from my husband's ACC. This is good I never recieved and was assured by the driver that it's cancelled. *****!!
