Still waiting for my order. Contact centers non-responsive.

I placed an order with Makro, which was scheduled for delivery on 6 August. Then received an email to say the delivery attempt had failed. But I was home waiting for the order all day. No one pressed the buzzer and no one called. I phoned the call center ant they said my number was incorrect. So I gave them the correct number. One week later there is still no sign of my order despite me sending several messages on the Makro WhatsApp line, call center and emails. I’m shocked by the service and lack of ability to at least give me an update. I have been waiting at home all this time but need to leave the house at some point soon. It’s not the first issue I’ve had with Makro. I really don’t recommend their online shopping service at all.
