Getting call but disconnects as I pick

Hello Sir/Madam

for last 2 days I'm getting calls on my mobile from number: 911206136800 and it seems from Noida (120) don't know. I have registered my number for DND. I don't know if it has been 45 days to it.

When this call comes, I pick the mobile and it gets disconnected

So May I know if this is a promotional call or after registering in DND promotional calls come but it disconnects when received.

Actually it creates a confusion as who the hell is doing all such nuisance

Sorry to bother..But it troubles if such calls appear to come

Looking forward to hear from you

Thanks
