Complaining about having to wait for a FREE router? Wow. That says a lot.
After reviewing the call, thecustomer does state that they would be using Netflix with the service. The agent responds with the streaming disclosure, including that the servicecomes with 10 GB of data and would slow down once the allowance wasreached. The agent also discloses the data allowance, including bonusbytes, during the pitch of the service to which the customer does not ask forfurther details about. The agent reads all terms and conditions in regards tothe data allowance, and the customer does not ask any questions in regards tothe fair access policy.
With regard to Netflix and the rep telling how long 10GB will last, they can't. There are too many factors involved, including the definition things are streamed in, what else may be using the data at the same time or even at other times, and I'm sure other things that I can't think of right now. There's just too many possibilities to give a concrete "This is when you will run out" answer, so they don't.
But, for your reference, HD normally streams at around 3GB per hour, SD around 700MB per hour and LD at around 300MB per hour. But, again, your system is going to be using data for more than streaming, so this only applies to the streaming itself, and those amounts are approximate, not set in stone.
