The worst service I've ever seen.

Me and my partner ordered something from Game (Kolonnade) and this has been my experience. I am extremely unhappy with how customer service handled the situation as well as their lack of professionalism and assistance. I placed the order on the 1st of December. I received an email with my order details and the email saying it will be delivered by the 6th of December. The 6th came and it was not delivered. I received no updates on the order. I enquired via the chat system online and they provided me with a tracking number which still did not give a delivery date nor information on where the package is. I received a call from the customer service department on the 10th and the women informed me that it would be delivered that day and she would follow up and call. I saw online that deliveries last until 7pm. The delivery address is a business which I did stipulate. The business closes at 5 so when it did not arrive at 6 I called customer support. The women, Anathi informed me it might not arrive on that day as I was told before by the same Customer support department. As we went back and forth she hung the phone up as I was speaking with her. I called back and a very friendly employee answered and discussed the matter with Anathi and informed me Anathi will call me back in a few minutes. Half an hour passed and i received nothing. I called again and Anathi answered. I informed her that i was waiting for her call back and she was rude. I asked for the couriers number and called them with no luck. The 11th, after I waited the previous day for my order which did not arrive I received another call from the game department. I answered the call and was met with silence on the other side. I hung up and called back. I spoke to someone who asked for my order number. I gave it and she mentioned something about it only being received the previous day. As I explained I've been waiting for it she also hung up the phone as I was speaking. The 16th, I am still waiting for my order and I am receiving no cooperation from the customer service department. Customer service is unable to give me feedback and neglected to give any as promised. Today, the 18th, I've received an email saying that it will be delivered today. I am still waiting. I'm very disappointed and frustrated with this.
