Reliance Communications — reliance big tv fake installation commitment

Dear team,
I have booked reliance big tv on 9th april 2018 with booking id 14543924 and that time it was ensured by reliance team the connection will be install with 45 days of booking date.

Till date i am waiting for the installation and whenever i called the customer care no. All executive gives the false commitment "sir aap ko hui asuvidha ke liye maafi chahte hai aur installtion within a week ho jayegi".

I have mark the mail in this regard to their mail [protected]@reliancedigitaltv.com but till date no one have some courtesy to reply the mail.
I never expect such kind of poor service from such a big and reputed company. It seems reliance is looted the public money and enjoying.

If any one from reliance pariwaar have little bit sharam then reply back immediately and resolve the issue.
