Disappointed in how customers are treated

We bought a Phillips iron from Game East Rand Mall last year in June and the iron stopped working in February this year, the iron was still under warranty so we took it back to Game in Greenstone Shopping Centre as this is the closest Game to us and the iron was assessed and we told it will take up to 3 weeks for us to get the iron back, this was on the 2nd of March. We never received any feedback from Game ever since until I called them on the 26th of March asking for feedback only to be told that the iron is still with the supplier. My issue with this whole thing is how this entire process was handled, 1stly we did not have an iron for over 3 weeks 2ndly no one calls us to inform us what is happening until I pick up the phone a call only to be told the iron was not even close to being ready, I had to throw a tantrum before our iron was replaced with a new 1 from the store which is something that should have been done before I even had to complain or throw a tantrum. The service we got from Game was really not what we expected from our trusted store that we always buy from.
