Online order nightmare

On the website, Makro indicates 2-5 days for delivery for items purchased. Received an email that reads delivery will be on 30 Nov 2023 (day 4). No delivery on the 30th of November. Phoned Marko customer care line on the 2nd of December. Their response was "feedback within 24 hours". No feedback or update on my order. Phoned again on the 4th and the 5th of December and received the same response. "Within 24 hours they will call me with an update on my order". On the 6th I've called again and asked to speak to a supervisor or manager. They transferred the call to someone who said he is the supervisor and also said he will provide me with feedback on my order. Needless to say I'm going to call them now again, because I didn't receive any feedback.
