Its a scam guys, I remember coming to bangalore for a job and the second thing I got was a new internet connection. These people were advertising everywhere, so I gave them a call and booked a connection. I paid 1000 installation and 2000 as deposit. While the guy was installing the internet was working fine, after he left the internet was gone and I never saw these guys ever again.
I called them many times and all they said was sorry we will come tomorrow but no one came. I had no internet for days and had to switch to another one. These guys are scammer. And the worst part is they sent me a bill due 1000 after 4 months. The nerve! These guys have no shame. Please do not call them at all.
