1.5Mb not MB is the speed and the cap is 100GB not Gb.
Anyhow this is the scam they are trying to pull:
We have no CAP but they "claim" we are using Business lvl internet and want us to pay for that,or agree to an "over limit charge" or disconnect us after 20 days.
I will monitor the bandwith and send copies of the emails from the ISP,my real usage,a formal complaint AND the bill payment to the Public Utilities Commission (doing this means the ISP can't lawfully disconnect for none payment).
