Huawei — cracks on glass on huawei p10 plus mobile set.

Dear sir,
I own a p 10 plus huawei set which was bought in kuwait in june 2017. I have been maintaining the mobile set in very protective way. The set has never fallen not even once neither has hit any where. For the last 4 months it is been seen that there are few cracks developed on the glass (Screen) on its own. I am surprised to see that a costly set of a renowned company product has suuplied this quality. I earnestly request you to please rectify this problem and what have i to do. When u see the set u will notice that it has no fall and the crack have grown time to time. My email id is [protected]@yahoo.com. My mobile no. Is [protected].
I expect a sincere servise from your end.
Kind regards.
