Reliance Communications — mnp harassment

Address:

Pune, Maharashtra, 411036

Applied for mnp on 19th sept. No response till date. Customer service is shut down. Sent mail to cust care. No response. My number is postpaid and i have already paid the rental in advance.
I want to port my number to jio. When i called jio, they informed me that mnp request is rejected and reason updated on their system is same documents not received.
When jio can inform me about this why can't rcom send mail / call / message me with requirements to resolve my issues.
