BAD SERVICE!! *********** STAFF!! ANNOYING CALLS!!

I placed an order online on the 29th June 2020 while it was on price shock Sale. The order was invoice got the statement and numerus calls enquiring when will I make the payment, how do I pay for something I haven't received??? Up to date I haven't received anything after numerous emails of follow up. An agent told me that the order has been returned to them because the courier didn't find me and is now out of stock what nonsense is that and my online account status still shows the order was dispatched and I never received an SMS or call from the courier that they are coming to deliver. How do you operate your business expecting me to pay for something that you don't bother delivering. Please adjust my account I don't owe you anything and advise what is really happening with my order?
