Vodafone — Vodafone is not letting me port out.

Address:

Nagaon, Assam, 782447

I'm a Vodafone user since last 2 years and its gave nice service before but from last few months the services started to get worse day by day and customer care officials were not helping so i thought to port to aircel. I did all the necessary steps to port my connection to Aircel and after 20 days my connection is not changed and the reason is that Vodafone is not letting my connection port out. Even after calling vodafone again and again they are not helping. Please help. My number which is to be ported is [protected]
