Uber eats

I have experience nothing but horrible experience from Uber Eats Johannesburg someone used my credit card credentials twice on their account with a credit card number that was cancelled 😞 and they never picked it up unless it’s an inside job I really don’t know all I know is I need my money back and no one from Uber Eats is responding so query. Worst experience ever I would never recommend them they are useless people must not register their card’s with if possible use cash what a bunch of *******
