Worst online shopping experience ever!

Terrible. I placed an order online on the 27th of November 2020 for 3 camp chairs and a gazebo. Today is the 22nd of December and I am still waiting. I was contacted on the 10 of December by someone at the Dawn Wing courier company telling me that game only dispatched 2 chairs and a gazebo and asked if they can deliver that so long. I told them no as this is an inconvenience. I'm not going to be sitting at home everyday waiting on my items that I received one order number for to come one by one. After this, I received calls almost everyday from people following up on this order and delivery. The last call I received was on Thursday last week, promising that she will follow up and get back to me the following day(Friday). It's another new week and the items I ordered for the long xmas weekend are not in my possession. Can i have my items tomorrow or my money back! I keep calling but I'm not getting any assistance!
