Vodafone Postpaid — Getting excuses for MNP

Address:

New Delhi, Delhi

I have a Airtel Prepaid number, i have applied for conversion it to Vodafone Postpaid, executive got my all required document on 27th Jan and said he will activate the number by the day itself, due to that i didn't recharged my Airtel number, after it everyday they are saying that the number will get activated next day, address verification has been done by one of the executive, on verification i saw that he was doing MNP for some another number([protected]) which is not mine. i called Vodafone PostPaid Customer Care (Mr Ravi) he said its take more than 7 days to convert the number after getting the documents and still they didn't get my documents.

Please suggest what to do...
