Terrible customer service

I bought a stove online on Tuesday. Till today Monday there no communication from them. I tried calling its engaging the hole of last week today a guy picked up and said nothing is showing on the system as to why it's delayed so he'll follow up with the warehouse. My worry is when I track my order its on j010 which is code for processing since Tuesday. M not happy with their customer service really processing the order for six days and no communication like even an invoice was not sent.
