DMart — Item missing

My order number is 55831342 and got delivered on Friday (7th Jan) but in that 5 items were missing. I complaint against it and I received the delivery yesterday (12th Jan). Yesterday I received the pending order but in that also still one item is pending. I don’t understand who is that dumb person who is handling the order please immediately change that person as he is incapable of doing this simple clerical job. I want either refund or the product immediately by tomorrow otherwise I will take this to higher authorities. I am seriously fed up with this pathetic service.
I have ordered 2 pears (4 x 125g) quantity but I received only one quantity.
I again complaint to Dmart yesterday but no response till now.
