Hathway — Regular 3-4 calls everyday for renewal of service

I was a hathway broadband user during between March 2021 and October 2021. I was using their service since I had taken a temporary office accommodation.

Once I decided to move from the location, I raised request for disconnection and the connection was disconnected.

However since last 8 months I get at-least 4 calls everyday with offers/renewal inspite of having my number on DND and explicitly telling the executives not to call.

The calls come from private mobile numbers and different numbers
