Questions about the acquisition of Ashe 19 Item Portfolio package items

It was really a bad shopping experience. I spent money in the game but didn't get what I wanted.There are two ways to purchase item Pack No. 19. One is to buy Ash skin directly at a cost of 1,800 gold coins; the other is to draw 10 combination packs to get 10 related items in the activity, but the price of combination packs will increase with the corresponding items I offer. It is also mentioned in the activity description that every time I draw a combination pack, it must contain 1 limited items and 2 standard items, so I should be able to get 10 limited items after drawing 10 combination packs, and I can definitely get the parachute action I want, so I am willing to spend 5600 gold coins to open 10 combination packs just to get the parachute action. However, after I opened 10 combo packs, I did not get the jump I wanted, and my combo pack collection progress was still showing 1/10,Why did I get such unfair treatment, other players after drawing 10 combination packs, they normally get the 10 limited items in the activity, but I lack the corresponding parachute action, i just want to  send me the parachuting action I should get, Please!
