Card not delivered - express delivery


Hello, I’ve ordered a Revolut card for a trip to USA this Saturday. I paid the £12 for express delivery which was due today (I am in the UK) but I have not received it or even got a tracking number. I need this card before I leave on Saturday. I have been on your inapp chat app for hours waiting to speak to an agent which ive given up on. Can someone let me know how to contact someone or get them to contact me so I can track this card delivery? So far the service has been poor and can see many others have similar issues. Not a great 1st impression of Revolut.
