Hathway Cable & Datacom — receiving legal notice message after 1.5 year of not using service

Hi, i used my hathway connection till first week of april 2017. As i was not satisfied with service of hathway. I decided to stop it. On 18 april, i went to hathway office in deccan, pune and paid the full settlement bill after having discussion regarding the discontinuation of service in hathway office in their payment machine. I have email copy of that. Hathway employee was agreed and said, they will disconnect it and will collect modem from my home and not to worry about bills as i am not using any service, so no need to pay bills and it's in their record. I stopped using internet before 18 april 2017 itself but still received bills without any reason after that. They collected modem after a year and now randomly getting such calls. It's causing me mental agony. Trusting hathway seems to be a biggest blunder of my life.
