TATA communication in CHI has 20% packet loss, how to open a ticket?

they have 25% packet loss, we do not have service directly with them and we have confirmed with our ISP the loss is not on the hand off and it is inside the TATA network

however they hardly exists does anyone know how to get ahold of someone?

ping to 63.243.129.120 are dirty and 63.243.129.121 are clean (i'm guessing the same box)

we vaey from 0% to 30% loss and it will run clean for 2-4 minutes then go bad again for 2 ish minutes
