Delivery Nightmare

I ordered stuff for my newborn daughter and was given a delivery date which I understood but much to my dismay as I track my order. It now states that it has been delivered and I’m ‘happy.’ How can I be happy when I paid and there’s no order delivered. I contact their help desk and I’m told it’s escalated with no updates to this hour. It can’t be a confusion of address cause it was a split order and got the 1st part of my order. I updated my new number on the app so I’m really disappointed that I’m being treated this way and I’m forced to improvise on items purchased for my daughter. I really want this matter resolved cause I paid and it’s my hard earned money spent.
