I have deactivated my Hathway account in 2021 and returned my modem and told them not to contact again . but everyday i am gettting 4-5 repeated calls to reactivate my account.i scolded them many times which is of no use . please let how to take legal action against them. i have already raised a complaint in conumer complaints board and no action was taken but the complaint marked as resolved . this is the last chance i want to give the next you will face me in the court of law i will take it further how much far it can go there is a limit you people are crossing that limit.
