May Amazon klap your business silly

I hope Amazon klaps your business after what you did to my order. I waited 2 weeks for my order, which was due for delivery on 3 November. On 2 Nov at 14h14 you change the date and try to deliver at 15h30 on 2 Nov, which of course I had not planned for and was not available. I told your delivery guy to either meet at 16h30 or on 3 Nov as initially planned, which he agreed to the latter. Imagine my surprise to find out that you had completely cancelled my order, while I was waiting like a fool for my delivery. When I call the contact centre, I am told that you cannot assure me that I will get all my items and there might be a price change!!!!! Because of your incompetence, I am penalised???? And this a few days before my birthday, you should be ashamed of yourselves...
