My email to Vonage (Score 1)

I am currently a Vonage customer. After reading this blurb, and some comments, I sent the following to their customer service department:

I am a current customer of Vonage, and am quite pleased with the service. However, I just learned that you will be testing some type of full page video ads on some websites. If I understand correctly, the video will be downloaded in the background while the user is browsing the website, and launched when the user leaves the website. Can you verify whether or not this is true? If not, can you explain the details? If the above situation is true, and Vonage implements these ads, I will find another phone service provider, and cancel my service with Vonage.
