Airtel — not receiving incoming calls and messages after mnp from vodafone to airtel.

Address:

Samastipur, Bihar, 848101

I ported from vodafone to airtel which was ported successfully on 24th of june but incoming calls and messages not working, outgoing works perfectly only incoming call and message problem.
I called airtel customer care and they said call divert is activated on my number, i checked there is no call divert activated on my phone.
They are unable to resolve this.
