Worse service ever dealing with ubereats

I have been charged for a delivery on the 10th of August and these useless people keep on telling me that my bank is responsible but my bank says it's them. They said first it will reflect in 3 to 5 working days and now telling me about a month and when I send them proof the *********** employee just brushes me off and it's worse because they dnt even have a telephone number where you can complain. I will be reporting them to the ombudsman and will gather a petition to have these companies not south african owned give a phone number and not let useless people that are in other countries handle issues that they do not know how to handle and all they do is sit in front of a computer and scribble nonsense as responses to people. This company really needs to be dealt with as I am also going to make sure that my lawyers deal with them cz I dnt tolerate nonsense and so should any south african having issues with this company. They dnt even have an email but are serving in this country how?
