TV Purchase nightmare

Purchased a brand new TV and have had to make in excess of 15 phone calls to move the process from Order placed to preparing despatch. I've had to call in multiple times to have the item picked which it still has not been. It is passed the delivery date and all I get from the call centre is that it is being escalated. There are not complaints channels that are being managed by an individual that is empowered in their call centre, their complaints are not even being monitored by management. I find this institution being irresponsible to their online consumers who will in future take their business to other online platforms who have their act together. I kept getting asked if it is for the Note 20 promotion, when it's a simple TV purchase, I can just imagine what is going on with the Note 20 promotion.
