Uber Eats ridiculous

I ordered from Uber Eats and it shows me that I am too far. I cancelled immediately. Then I got an email stating that I need to pay R100 for cancellation after I cancelled within 5 seconds. This is unacceptable as it is not my fault due to I am too far. Why the order did went through if I am too far. They must take the R100 off my account and delete my account as I will never order through them again. This is just pathetic. There are no contact details on the internet for Uber Eats and the email I received from them to pay the R100 was ***, *** and ***. I have sent email to both accounts and all the emails bounced back. They are very quick to send me an email for money, but no emails working. What service is this? When I phone the restaurant they said that Uber did not cancel my order.
