FastWay Transmission — for discontinuation of set top box

Myself dr simrandeep singh from chandigarh. I have white colour set top box, using this since may 2018. I had submitted request to discontinue set top box 1 month back. Request number is 28102018w2615932. No action has been taken till 2 december 2018. I called many times fastway customer service but no proper response from fastway. Today i called fastway customer service mr kamaljeet gave poor response and my call transfer to team leader mr vijay. He also disconnected my call in between. These guys making fun and worthless at their job. I need immediate effect for my discontinuation of set top box and pick up for the same. Kindly make sure too that my refundable amount will be back on same day.
Thank you
