Reliance Jio Infocomm — Disconnected old connection and installed new connection.

I was having a jio fiber connection for more than a year. On Oct 11th, I was out of station. My son was at home and your sales person Raj came and said he is installing an upgraded setbox and will get refund of my advance of Rs.2500/-. He also said if we pay an advance for 3 months, 4th month will be FREE.! He also assured to get vouchers for the remaining 10 days (viz 11th to 20th). What he has done is HE HAS DISCONNECTED MY OLD CONNECTION AND INSTALLED A NEW CONNECTION IN MY SON'S NAME..!! I have not got refund of advance also. I lodged complaint through customer care on 23rd Dec but NO RESOLUTION. They simply CLOSE THE COMPLIANT. I call them and then they again reopen it..!! (SR00001G7H2B & SR00001GAVZS). Just to boost their sales THEIR SALES STAFF ARE DISCONNECTING OLD CONNECTIONS AND INSTALLING NEW CONNECTIONS..!!
