Hathway — Hathway Cable - Mental Harassment Telemarketing

I am getting regular calls on my personal number from hathway to start a renew connection from unknown numbers. It is extremely annoying even the telemarketers are disturbing at the busy time. They are wasting my time and causing mental stress. I will raise a police complaint for the mental trouble they keep giving me, if this is not resolved.
They keep calling from different numbers. There is no true identity as who is calling. I don't think someone could just like that call my personal number. It's punishable offence as they keep calling even if i requested them to stop. I have records of at least 4 calls everyday as proof I've attached a file of them calling me from unknown numbers.
