Hathway — unnecessary calls and mails

I'm a subscriber to hathway broadband and i asked these guys to deactivate my account.. They even told that they will update the account.. Yet these guys are calling without any reason.,. They want me to renew the account.. Why the heck should i do that im not even in that place.. Such a miserable service.. Such a garbage

I even have proofs that i have mailed these guys to stop sending messeges and calls.. Yet i dont understand their problem... If for godsake anyone o[censored]r hathway guys seeing this... Just deactivate my account as mentioned above... Just dont call!!
