Unsecure Network and hard to get in contact

I was reluctant on using Uber and was finally convinced to give it a shot - 2 days after using the app and taking my first ride my credit card was compromised and hundreds of "rides" and "UberEats" charges are being made in a different country!! Cant find and email or phone number to contact someone about this and I am unable to delete my credit card details. Someone did call me but charges are still coming in.... so frustrating! Will delete the app as soon as I can clear details and not use Uber again. So disappointed
