Reliance Bigtv — delay in installing new connection

I have booked for a new connection from Reliance BIG TV on 01.03.2018 Booking Id[protected] got confirmation via sms from them that it will be installed in 30-45 days and after crossing of that deadline i requested them numerous times for installation then i registed complaint in National Consumer Helpline http://nationalconsumerhelpline.in/ (Docket/Complaint no-692364) on 17.04.2018 they told me to sent a mail to Nodal officer of Reliance Big TV for immediate action but he never replied then on 22.05.2018 they adviced me to register complaint on PGPORTAL https://pgportal.gov.in/ (Complaint/Registration no.-MOIAB/E/2018/01221) for a strict immediate action on them which i did.
then on 29.04.2018 i recieved a call from RBig Tv peoples after they recieved my complaint through Pgportal they promised me to install connection in 4-5 days them to my surprise after lapsing of that period i recieved a mail from them which says that they are glad that i am ready to wait for the connection but that mail didnot mentioned the 4-5 days of wait as promised by them which is really misguiding on their part

Below are some of the email ids for sending complaint to RBIG TV
