Paid, damaged and now playing games

I ordered an item online, which was delivered timeously. Unfortunately the item was damaged. I have logged a return and exchange, which is supposed to take 2 - 5 working days. I am now on day 7, without a usable table, and Makro and their supplier are playing a game of who's fault is it, before they can let me have my undamaged table which I have paid for. I keep getting told, someone will come back to you, and radio silence. This is simply unacceptable. If Makro are unable to manage their online department, perhaps they shouldn't have one anymore.
