I never expected that I would be cheated by entering my details on airtel website

I am from Mumbai-Thane. I had updated my number and name on airtel.in website for getting new HD DTH connection.

I got call from Sunil Goswami (sunil.g@vriti-interactive.com) from this number 0120-4087612.
He told me that I will get connection (Mega Pack with HD for 12 months and plus one more connection of normal dth 12 months subscription, 250rs cashback on each) for Rs. 7870
I paid 7870rs with Kotak netbanking on 23th September using Payment Link connectindia.in/checkout.htm. Reference number is 3979216
He promised that by 24th September evening I will get the installation done but nothing happened till now.
There is no customer id generated for me till now.
All my STD calls and emails to vriti interactive were unanswered.
No idea why airtel is entertaining such fraud illegal thrid party fellows.

I have googled for vriti-interactive and my heart dropped by seeing the number of complaints registered on it and airtel dth combined. That’s the reason I am writing this email.

Please see to it that I receive the connection with specified package as promised. If not please return my money back.
