I have two postpaid connections with Vodafone and I am not happy with the services of Vodafone hence I wanted the upc but as per the trai policy, i[censored] are having a family plan, u need to delink your account and then u can get the upc code, hence I called 199 and informed them that how can I delink it, they are telling me that I have to take 499 plan for my primary number forwhich I am am a currently paying 399, they are so stupid when a customer wants to leave them, instaed of asking the reason they want to increase his price plan
