Samsung — Samsung Note 9 Display under Warranty

I have your premium model Note 9 purchased last year in november 2019. On 13/10/2020 suddenly the screen turned greenish & there were lining & fliker on the screen. I immediately rushed to the service centre as my phone was under warranty & i submitted my phone for repair under contract no [protected]. Today i.e 22/10/2020 still there is no update as too when i will get my phone, the service centre people says that the part has been ordered and it will take further a week but no assurity that it will get my phone. I have invested considerable amount to buy this phone. Please... I need an immediate solution to solve the display issue.
