Hathway Cable & Datacom — not deactivating my account and calling me daily twice with new offers

Address:

560034

Hathway people are calling me twice every day.
My account no. Is [protected].

I have faced many problems with hathway. I have raised complaint before as well.
Finally, i asked hathway to deactivate my account before a week of my data pack expiry (November 2018). They ignored my mail. Now i am using another broadband connection.

They have still not deactivated my account and calling me daily with new offers.

On every call i tell them that i don't want these calls, still they continue calling. They are playing with customers privacy.

When i was a customer, they were not replying to my complaints. Now since i left, they bug me daily.
