Ubereats stole money from my bank account

Ubereats SA does not have call center so we can not report issue anywhere in real time. Their help link does not even ask for specific details only tells you about frequently asked Q. I have sent tweet to them but action taken. There is over 5 transactions that when out of my account additing to about R1500. I have had to stop my card but still no clear indication what did i buy. I am now thinking the **** is within ubereat and would like answers
