zero out of five star
soo much bad service after installation
there is always speed issue and alsow no internet access
& customer care serice is alsow bad they even can't answer in manners. some times they said "nai hoga apko jo karna hai karlo"
no replys of email and complaints.
i already face the issue from last 3 months and still now they can't slove the issue.
