Poor service. Little to no communication. Unreliable.

I ordered a phone from Vodacom last week and I was told that I would receive my order on Friday. On Friday I didn't receive any communication regarding the package and gave them grace at least until the next day. When I tried tracking my parcel I realised that the update on the site showed that the parcel has already been received but I did not receive the parcel. I then proceeded to take the issue up with Vodacom and I was told they can't do anything about it as the phone is already with the courier company. I then tried contacting the courier company and failed to get through to their line for several hours. When I eventually got a hold of them I was told that I should be expecting my parcel on Monday. Monday was the same procedure... no communication whatsoever and Me trying to get a hold of them and trying to get to the bottom of this issue. I was then told that someone delivered the parcel but the receiver refused to take it. At this point I'm so frustrated because I have been expecting my parcel and literally made sure I can see when someone is in front of my yard. So I inform them no one was here to deliver the parcel and again they told me that the parcel would be delivered on Tuesday. Guess what? the exact same thing happens on Tuesday... No communication from them and bare minimum updates on the tracking site. Today they delivered my parcel but I was told that my proof of residence is not valid and they would come back in 30 minutes so that I can get it sorted out. they even gave me their number to call them when I'm home. I managed to get everything done in 15 minutes and tried calling them back but to my surprise no answer. I am slowly but surely running out of patience and super frustrated. Online shopping is supposed to be convenient but this? This is just super annoying and disappointing.
