We do appreciate the loyalty you have had to the Verizon family over these past 15 years. I'm happy to hear that Ryan was able to get your order placed correctly. I have forwarded your feedback to my leadership team, and while your feedback and the outcome are all handled internally I can assure that your dismay with this experience will be heard.
"Customer of my level" This and the attitude of the post suggests details are missing with how the interactions went. I've been a customer just as long and wouldn't dare take my anger on another rep demanding supervisors because of a previous interaction.
Also, who orders near a holiday and expects fast delivery? Even standard 2 day shipping has been delayed some parts of the country due to Covid-19.
15 year tenure or 15 months, no one is above anyone else.
