Horrible customer service

Uber eats took R900 from my account on the 26 of February without authorisation from me.I have been trying to contact their agents for 4 days now and there’s no reply from them . What a horrible service.They just copy and paste the same thing and ignore your for 11 hours only to copy and paste the same message from yesterday.They don’t even have any number that we can contact for help .Just social media pages where they don’t answer but they always have time to post content.Please remove your bank details from Uber eats.They are very horrible
