Salesman Lie to get you in contracts

I called multiple different sales people to make sure I was getting accurate information. I told each one if them we used over 250 gb a month. We have six people with phones, xbox, alexas, printers etc. I told them we average 1-3 mbs with current internet but average about 1.5 but would like to be able to have more than one person using it. They each said that we would not use as much data since it was faster, ok but I know we will use more than 20gb, how slow is the slowest it will be once reach cap. I was told by more than one sales rep it will never go below 3. So that was twice as fast as I was getting so it was worth the $30 more a month. They give you more the first month so that you will not realize how slow it will be. During my probation time I called telling them it wasn't working quite right. They had a technician come out look at dish, then ended up moving router upstairs. But the time it took technician to get appointments I was past the time to get rid of it. I call one to two times a month constantly having issues. Today we were at 0.15mbs. I called hughesnet and they couldn't even test my speed. They told me it wasn't working on there end to call back later. They quoted their favorite line you have reached your cap. I have been promised three separate times that i would be given 2 extra gb to help me get through my situation to get me off the phone. Never got the data. I will make sure everyone I know, will understand about the salesmen lies. I have 4 kids, two times they got Fs on homework because they could not access the videos they needed. We have been told also you have too many devices. They tried to tell me this today I laughed because I only had one device connected. We can just surf web with no video and our data seems to disappear. We are stuck for 15 more months. We cant afford to get out. I wish I never would have switched. It might be in the fine print but its shoukd still be considered fraud.
