Uberears are ****mers

I placed an order and paid for it by card with Ubereats on the 9th February 2024. 5 minutes later ther order was cancelled . I received a message on the Ubereats App that a problem had occurred and I would receive a refund within 3-10 business days. It is now 6 weeks later and I have no refund. The App only allows you to chat to an automated service which resolves nothing. I have not Bern able to find a working email address or phone number to address this problem. I am wondering how many other people have been ****med like this
