Hi ilmontgo,
We're very sorry about this. I was able to locate the call where you were offered the upgrade to Gen5 and did indeed hear the agent state the "No Hard Data Limits" speed was up to 3Mbps. I scoured our knowledge articles and could not find this information being provided to the agent, so we will definitely be going back to them and ensuring they understand the features and specifications of the service.
Regarding the varying speeds after exceeding your allowance - traffic is categorized into different types, which is used to determine what our customers need most. When your allowance is exceeded, not only are your speeds slowed down, but certain activites may see further restriction (HD video, frequent file downloads, video chat). This prevents other customers who do have data from being affected by the few heaviest users. I recommend reading our network management statements here: http://legal.hughesnet.com/NetworkManagement.cfm
If you'd like to keep the Gen5 service, I can see what I can do as far as getting the price lowered because of the incorrect information you were provided by the representative. Should you wish to cancel, we understand and would definitely waive your early termination fee.
Thank you
Amanda
