Vodafone India — portability issue

Address:

Ernakulam, Kerala, 682504

Have requested for mobile number portability from idea to vodafone. After then vodafone executive asked the proof for the connection. I sent that proof to their email id on 24/07/2017 but still now the formalities not done by them. They didn't ask my photo, my signature. Also they not yet visited me. The executive told me on 29/07/2017 mnp will done. But how it is possible, without my photo, signature, how did they completed the process.
