Left after asking to wait

The rep came like he always does. I was busy placing an internet order and asked him to wait until I have completed it. He then said that he is in a hurry. I again said he must please wait I 'm just finishing up. He then again said he is running late he has to go and threaten to leave without finishing my order. I again told I'm almost done. Then he started complaining to my packer. Then I rose my voice and told him he must just wait I'm almost done. He then left. This all happened in 15 minutes time maybe even less.<br> I went out too his van to ask him if we can place the order. He ignored me and left.<br> I phoned his office when they put me through to his supervisor I held on for 10minutes but, the phone was not picked up.<br>
