Incredible, I think NOT

I ordered a product online from incredible connection on 22 November 2021 at about 12:53. When I started tracking the order I saw that it was picked up and handed over to the courier on 23 November 2021 at 8:45. I made special arrangements to ensure that someone would be home till Monday, 29 November 2021 as this would be the 5th working day after the order was placed (as you state shipping can take till 5 working day). I started getting nervous on Monday as no one had contacted me to confirm a time for delivery. I then phoned the service number at 10:47 to explain that i need it to be delivered as this was the 5th day and that i made arrangements. A complain was logged. After receiving no communication about a delivery I phoned again at 12:33 and again explained my situation, the person said that if it is not sorter on Monday, it would be on Tuesday. I was upset with this news. On Tuesday 30 November I phoned again at 8:12, explaining my situation and that i could arrange someone just until 10:00 to be there to receive the parcel, the person on the line said that it was escalated, but still I have not hear any news back. I then stated that i would like to speak to a manager to get this issue sorted but the person could not help with this request as you are working from home, but she said that she will indicate it on the system that someone should phone me back. As I have not hear anything I phoned again at 9:50. Still no answers could be given to me. That evening, I sent a email to them as well to inform them about my troubles. With no one phoning me or responding the the email, I phoned again on Thursday, 2 December. I was just told that on my profile it says that someone should assist me urgently since Monday.

I am really out of options to what else to do, I just want my product. :(
