Very disappointing service

I placed an online order with Makro Strubensvalley, delivery was expected on the 2nd of Dec. I hot a text that they will deliver on the 1st but they will call to check my availability. They did not call. I called to notify that I am not home and delivery should take place on the 2nd as the app says because I was not home. Till today my order has not arrived, they don't answer their phones. I called the national customer care, still no movement. What the hell is this??
