Delay in delivery and no answer when calling their call center

I ordered online from Makro the 26 November 2021 , when contacting their call center their phone just constantly rings, when I called the call center and finally got through, I enquired about my delayed delivery, I was told I was being impatient and that it would be delivered over the weekend, today is the 6 December, I was contacted and told they don't have two items when checking online they changed more than two items, poor customer service, their online platform is bad, and disregard for their customers.
