Vodafone India — mobile number portability issue

Address:

500008

Porting request: va145297
Rejected reason: this post-paid subscriber has outstanding payments due.

Even after clearing all my mobile bills vodafone added one more pack after portability request without my knowledge and showing it as pending payment.
When contacted customer care they said its done by retention team. This is pure malpractice and wrong from vodafone.

Note to vodafone: please find better ways to retain customers than cheating them with wrong bills
