Very, very poor customer service on no delivery of my online purchase

Very poor service from Outdoor Warehouse customer care and online sales management. I bought online from Outdoor Warehouse a National luna fridge. Coming Thursday 01 September 2020 it will be three weeks since my purchase. They send my purchase to the the wrong town in the wrong Province! (According to them I have entered the wrong postal code: address is correct) Every time I phone they put the blame on the courier company (Dawn Wing). Regardless there is no other effort like for instance sending me a new order and have the courier company return the original order to them. No effort to keep the customer happy! Only empty promises. For the last week I have been dealing with a manager and same story, waiting for feedback from the courier company. Regardless if it is my mistake by entering the wrong postal code which were an error as I pressed 5 instead of 8, which is below/above each other on the keyboard. (Human error I admit) It has been 7 days since I first made contact with them and still the only comment I hear is we are waiting for feedback from the courier company (Dawn Wing). Today the manager gave me the blame because of the one digit mistake I made accidently on the postal code. The fact of the matter is for the last 7 days I have accomplished nothing. Do not purchase anything from them online. I will never buy anything from them, not even in a store! I leave for my trip in a few days and still have to have the fridge fitted and wiring done.
