You are asking for a legal advise here... Wrong place. Besides, you
don't suggest the country in question, so even a qualified lawyer
wouldn't have enough information to give answer as to the legal right of
the ISP.
What I'd do: see if same happens with other customers of the same ISP,
and if that's the case - give business to another ISP. Sure there's a
possibility to work around this but what the hell.
