Hathway — Numerous calls from Hathway even after accepting surrender request

Address:

bangalore

I submitted a surrender request to Hathway and the online portal shows that it was resolved. But still I receive more than at least 5 calls a day proposing some offers and asking the reason for surrender. I requested them politely so many times to collect the modem but still they keep calling me endlessly from different numbers. This is w.r.t account number cable TV [protected] and broadband [protected]. I already moved to a different service provider.
