UnCapped not as promised in Original Contract

When I purchased this package nearly 4 years ago I was assured that it was uncapped - a few weeks ago I was offered a new modem, installed and after a while my internet slowed down and then stopped completely - My suspicion is that the new modem was sent in order to monitor my usage<br> <br> I phoned technical services to be told I had been \throttled"with no warning - who BTW were also not helpful and did not seem to take my complaint seriously<br> <br> The technical guy said there is a \""fair share\"" policy which I know nothing about.<br> <br> I was then offered a new product to pay more money to get more gigs!!! but was told that would only give me 20 more so \""its not really worth it\"" - I am so frustrated I can hardly write this properly so I hope it makes sense <br> <br> I am very angry because I now do not have the product I was promised and no warning after FOUR years that upcapped actually does NOT mean upcapped!!!! as I was promised after repeatedly asking what's the catch <br> <br> <br> If I had been told there was I new \""fair share policy\"" I would have changed to a company that keeps its promises and if this \""problem is not resolved I will look elsewhere """
