It is always important for a prospective customer to research a product or service before they purchase it, and that's especially true of the latter. No one should go in blind, nor should they solely rely on the salesman. Salesman are there to sell a product, not promote its limitations.
Streaming can be done, but like mentioned, this service is not meant for cord cutting. Per Netflix, streaming in HD uses up to 3GB or more per hour, SD up to 750MB or more per hour, and LD up to 350MB or more per hour.
If you're running out of data your answer is to use less data. No one has to buy tokens, nor to they have to get to the point that they would need to buy tokens. When you run out of data your service speed is throttled, like you're finding out. FAP speed, the Fair Access Policy being what you're subject to when you run out of your plan data, is officially "As low as 1MB or lower."

Additionally, no speed is guaranteed or promised. The 25Mbps is an "up to" speed.
Lastly, please respect the fact that this is a public site, with many people reading it. There is no reason to use foul language.
