Worst customer service experience

I ordered phone online, reflected as delivered on their system, while I was not in possession of that item. So I contacted numbers reflecting on their website which led me through to online department. I was led to their Rosebank branch.The customer service at their staff from Rosebank store is disgusting( they know meaning of customer service let alone telephone etiquette or business ethics), I called in to follow on order which was purchased online, they were not helpful to a point their said if he doesn't want to assist he won't and even threatened to hang up phone which he did while I was still holding phone thinking he will check on their systems and advise accordingly. Their head office staff are also incompeted as they kept on hanging up instead of putting me through to complaint department. From 9am to 3.30pm been trying to get assistance from these people. I am so disappointed I'd never recommend anyone to purchase online at Game.
