Essential Printer not delivered in 5 working days

Bought a laptop/printer combo on Game online site on 17 April 2020. I had no feedback on delivery although after I bought the combo, I phone the helpline and the lady told me that it will be delivered in 3-5 working days. I phoned on Tuesday and spoke to Anti who said the laptop is non-essential but the printer essential and she will phone me back to indicate why it was not delivered yet. Anti never phoned back. On Wednesday I phoned again and spoke to Malika who told me the same story and did not phone me back. I also emailed twice requesting feedback and supplying the links where laptops are now deemed essential. Thursday, I spoke to Rene and Rene informed me that they do not have stock. This is where I totally lost it as it will take 2 weeks to get my money back and they do not know when they will have stock! And then I get patronised further with phrases like "I know your frustration”! Why do Game advertise things they cannot deliver or do not have stock off? This is unacceptable no matter how many times you know my frustration as I feel you do not know my frustration. My frustration is that 1. People do not phone back when they say they will 2. that Game sell things they do not have 3. I must phone Game every day to follow up on a delivery that I have to pay for.
