Swiss Chalet complaint: 3 hour delivery wait

We placed our order for Swiss Chalet as we do almost every Sunday. They noted that this time there was no arrival time. However, the delivery time is totally excessive – the order was placed around 1730 or 1740. I called to see what was happening around 1930 and was told it wouldn’t be long it was on its way. Here it is 2030 and our order has not been delivered.
We order almost every Sunday and this is totally unacceptable – 3 hours for a delivery under any circumstances is simply unacceptable. Shame on you.
So at 2030 I called to cancel my order, 3 hours is just too long and was told that my order had been cancelled apparently saying I had cancelled which I absolutely had not done however, I did just cancel although I had not cancelled before because the woman assured me it was on its way and would be here shortly. Now I am on hold for the last 10 minutes for a supervisor
