Reliance Communications — reliance communications - mental harassment (not, new does it to all its customers)

Kindly note

I was holding reliance mobile number [protected] at mumbai. I had requested mnp on 6th april 2017 & at that point of time, the customer care executive told me that mnp will take effect in a few days.

The last bill i have received from rcom is dated 1st may 2017 of amount 574/-. This entire amount was paid dated 3rd may 2017. As full & final payment, as i ported out from rcom. I have not received any bill after that. What i received is an e-notice from shadab peerzade.

Is this a fair practice that rcom is following? I plead you to take appropriate action against this. This is causing mental harassment. And if any accident takes place, reliance communications will be solely responsible for all the deeds.

Please help.
