Appalling Customer Service

Having been an on line shopper with Sainsburys for a long time I have just had an experience that has put me off them for life.
I had a delivery expected for between 8am and 9am. When nothing had arrived by noon I phoned to see what had happened.I was told that the driver had called at 8.45am.
Not true we were actually standing outside our house until 11am.No one turned up at all.I was then told that no delivery could be arranged for the same day and that it was up to me to 'phone a different number to re-book the delivery for another day!They were not even prepared to do that for me.
They had taken the money from my bank account so that my wife and myself who are both in our seventies could not even go out and get a bit of shopping.SHAME ON YOU SAINSBURY'S!
