Slow delivery and bad attitude

I placed an online order today at 12:06 pm. Order number: #5349-667.At 13:06 I still had not received my order. I phoned the store and the cashier claims they did not have my address was, even though I am a regular customer. On inquiring when I could expect delivery, I was told that it would be another 40 minutes. I told him it was unacceptable and that I wanted my order for free. He then transferred me to another person. After having to extract information from him, I found out that he was Douglas the manager. I then asked him why my order was taking so long. He started to tell me about online orders going through some system. I cut him off and told him he was talking BS as I always order online and it never takes so long. He became belligerent and I ended the call. We then phoned customer care. At 13:40 I received a call from Douglas to say my order was on its way. I again complained. He told me the system did not show where I lived. I told him that I am a regular customer and all my details are on the system. He argued and I told that it was just stupid. He again became belligerent and told me I could now phone customer care again and tell them I called him stupid and hung up.
