UBER SUCKS!

I purchased 88 vouchers for an virtual function this week and some of the vouchers would not work. When calling the help line number I was told that because I am using them for Uber eats they can't help as it is not up and running as yet and was advised to go through the app. On going through the app you are advised to contact the person who sent the voucher. This did not help as I purchased the vouchers from a store. i then contacted the store who sent a mail to the barcode company bluchip who came back advising the same number I contacted in the morning. Really, what is this a joke. An event ruined because UBER do not take calls personally and problems can not be solved at all. Never will i use this system again. I am left highly embarrass. I also see that they do not respond to the Hello peter complaints. This is what I call corporate arrogance 101
