Website:	www.amazon.com

I have ordered s product order id[protected] on 26th november 2018 from my amazon account they said that the product will be delivered with in 10th-13th december 2018. I have done the payment and i eagerly waited till 13th december but when i contacted to the amazon customer support they are saying that the product is cancelled and the refund will be initiated soon. Without any intimation they have cancelled my product. But i want that product. I have wasted my time waiting for the product. Even i want that product. I have requested them lot of times and they are not solving my problem.
So want to give a complaint on amazon. Please help me to get that product as soon as possible
