NEXUS 6P - DISAPPOINTED CONSUMER

Good Day Huawei It is with great regret and sadness that i have to write this review. I've recently been able to purchase a Nexus 6P (with a great deal of effort and time on my part), but after less than a months usage (19 days in fact) the phones screen is inoperable. On its 19th day of usage it developed a thin green line along its left edge., as the day progressed the one line turned into two and but mid afternoon the screen went completely blank. Ill remind that this phone is meant to offer premium quality and usage (at a premium price). I'm sure it will come as no surprise you that I am thoroughly disappointed and concerned. Please advise on a way forward as i would like to resolve this matter with haste and with the least amount of hassle Regards A Disappointed Consumer
