Hi @Gjgfv, sorry to hear about this.
In this case as the screen is both damaged and displaying unwanted lines, my suggestion is to get in contact with your local support team. They can help you to have your phone sent to an authorized service center to be physically examined. If you have any questions regarding the service, such as routines, warranty and consumer laws, these type of questions are best answered by your local support team as well, as they vary between markets.
I hope that answered your question!
