Hathway — Getting calls frequently from hathway

Hi,
My name is Ramesh.Tanamgari
. I took hathway connection in bangalore and I vacated house in bangalore and recently I couriered hathway device to bangalore house address even though I'm getting calls frequently from hathway. This makes me disturbing daily and irritating also.
Please take necessary action and do the need full.
