The worst after sales service ordering online!

I have ordered a 4 plate gas stove from Makro on 13 Jan 2025, it was delivered on 17 Jan. On the 'Sale package ' a regulator, pipe and two clamps are included. However, the stove was missing all of these, and can not be connected to the gas supply without it. I reported this via email, and phone, to the Makro support team. I was told to lodge a return on the app, which I did. Up to date I have had NO feedback or contact from Makro, nor was the stove picked up for 'return'. This is the WORST AFTER SALES SERVICE!!!!
