Consumer Redressal

Dear Sir/madam Today I got my bill of Rs.37,681.83 for the period of 29th November 2014 to 28th December 2014 from Vodafone. In this bill I have been charged for Data usage charges of Rs.35733. I am surprised to see that my billing is done considering the Vodafone Red Plan activation date of 12th December and Data usage charges have been charged as per the normal rates. But I would like to inform here that I requested on 24th November to activate the Vodafone Red 1599 Plan on my number which was never got activated. As per the information received from Vodafone is that Vodafone Red Plan can be activated only from the Billing cycle date then Why it was not activated from my Billing cycle i.e. 28th November???? At last it got activated on 12th December after rigorous & continues follow-up with you guys. Why I am being harashed by sending such huge amount bills for the mistake done by Vodafone Technical Team???? Why should I pay this amount for the mistake done by vodafone??? Also make note that as per Vodafone 1599 Red Plan I have been given the contact details of Relationship Manager but regret to inform you that whenever I tried calling on this number it was always unanswered. This is cheating when you commit something as a part of the plan which you are selling then I should be proper.
