Unhelpful and Unresolved

I called the branch this morning regarding the Mindy Dome Felt Hat code HA0860 (not available at time) which I went to purchase 3 weekends ago. The hat was out of stock as it had just gone on sale. I asked them to please call other branches for me, the lady who assisted me did so begrudgingly as they had no code on the system, she called 2 and refused to help further, she also stated that I should have purchased the hat the day I saw it. I then called every branch in Gauteng and CT until I found it in Woodlands, the lady in that branch was really helpful and said she would send the hat to Eastgate for me and attach my number. I called Eastgate once a week for 3 weeks to hear if they had receieved it, each time they would be rude and not take my number or check the stock for me, basically I was wasting their time apparently. When I called for the 3rd time on 31 July I was told that they could not find the hat and that they had probably sold it and there was no stock left. I just find this shocking, I went through the effort to find it and get it delivered, all they had to do was phone me to collect it. I need the hat urgently for a wedding and still have heard nothing from them.
