What should I do?

So I'm doing a 3000 calories per day diet and I bought muscle tech mass gainer and it says per serving is 5 scoops and total calories are 1000.. the coach told me to take 2 scoops which mean 200 calories so I'm taking twice a day which means 400 calories and 400ml milk twice which means 468 calories so I only get like 868 calories from mass gainer and I want to get more calories from it so that I will eat less because I can not eat more food and I can't even take more scoops because people told me it will affect your body so what should I do?
