Vodafone — Very bad and irresponsive services

We have been taking services from Vodafone from past 1 year. When we choose to port our services to other service provider and had cleared our dues before hand they still haven't updated on the portal from their side. They have been really irresponsive from their side and the relationship manager which has been provided by the Vodafone has been very bad with the services i.e., Govind Nikam.
Due to which our business have been hampered as we work in a client centered services, behavior like this is not acceptable. We have been trying to connect from past few days but hadn't got any accurate answer for the same.
I would like to request Vodafone to look in this matter and do the needful for the same as soon as possible.
