[Resolved]  Hathway — calling frequently

Hathway is calling frequently even after i returned modem as i was not using the service there are torturing me i don't why. Is using a hathway connection is sin in my life such a worst internet service provider don't know how to treat the costumers. I am suggesting all of the people while using hathway is ok if you don't use they will torture with unnecessary calls and send the illegal notices to the customer such a worst network is hathway better to go for act fiber even it is more cost because they provide good service where hathway provides good torture to customers.
