Over promise and under deliver

I recently upgraded on my contract and Vodacom delivered the phone on the 1st of September 2021. On the 4th I called their after sales department and requested to change my phone as I thought I took an iPhone 12 pro max .The lady that was assisting advised that thy can come and pick up the phone and I will do the whole upgrade procedure again .She advised that it takes 7 days for RAM to come and collect .I am writing this on the 7th day at 5 pm and still haven't received a call from Vodacom or RAM .I am going on a vacation and I would like to get this whole process done ASAP as I will not be around JHB when you finally decided to come and collect the phone .Also I would appreciate if you would stop wasting my time and bring the phone that I want when u come to collect this one .

What ****ed me off is that I received my statement today and I am expected to pay for a phone that I am not even using .Well guess what ??? I will not pay for anything that is not a iPhone 12 Pro max .
