Upgrading of contract and unacceptable behavior of the complaints department

My wife upgraded her current contract to include a new iPhone 17 Pro Max. The sales consultant mentioned that 2000 units are delivered every Friday and that we should receive the device between 3 and 5 working days since we phoned on a Wednesday. After following up with Vodacom they mentioned that they have a backlog and that we can expect to wait for a month. The expectation from the sales consultant that was created was 3 to 5 working days. After finding out that the backlog is 4 weeks I phoned the complaints department where a very rude lady answered my call. I expressed my disgust and requested a reference number for the complaint but the lady refused to give me one stating that they don't give reference numbers which is odd since you always get a reference number for any call made to Vodacom. I asked the lady if I can speak to get supervisor after which she rep**** that she is working remotely and does not have a supervisor. Everyone has a supervisor unless you are the CEO. I ended the call and called the complaints department again after which the same lady answered. I again requested to speak to her supervisor and she hanged up on me.

In conclusion, the expectation was created that we will receive the device within 3 to 5 business days only to find out it will take 4 weeks. The utter rudeness of the lady in the complaints department is not what is expected from Vodacom but seems to become the mainstream norm.
