Useless internet from Paratus

We live very far from any big town or major center, so internet options are very limited. We have been using this company for more than a year now and since day one we have been struggling with them. We pay quite a bit of money every month for 10mbs but most of the time we are lucky if we get even half that speed, some days we have to be happy with a third of that speed. Just about every day I have to reset the system just to be able to get online. It is so bad that I can't even link 2 security cameras to the wifi. What makes it worse is that we operate a small lodge and regularly have to try and explain to clients why the internet is not working. Every time I contact them, I have to waste hours of my time with them on the phone, answering the same questions and running the same tests and it's always the same excuses, but no matter how many times I ask, they refuse to arrange for a technician to come to me and properly check the system. They would rather try and convince you to double your speed package (at double the price of course), which my neighbors did and they are now having even more problems. They simply don't care about their customers, especially out here because they know we don't really have any choice.
