When I was living with a roomate, we took hathaway internet connection for 6 months. After this period, I moved away, replacing my registered mobile number with that of roommate. This was in March 2020. Now in Spectember 2020 they are calling me 2-3 times daily to recharge my account. My number is not registered anymore, but still I am being harassed by their calls.
