[Resolved]  Vodafone Postpaid Mobile A/C — Incorrect information provided and undue charges applied

Hi,
I have a postpaid mobile A/c with Vodafone. This is corporate card I got when I was an employee of 3Global services pune. Now they said its compulsory to be on Ecs (ie. bill ammount gets deducted directly from bank a/c) because that is policy of 3G. Now for the first 2 bills the ECS was not active. When it became active for the month of Dec 2009,I had changed my job with Amdocs and i have a new bank A/C now, I did not have the time left to change my a/c details with Vodafone as it is supposed to be done3 days before the payment due date. My bill was Rs.437 due by the 20th dec 2009, so i deposited Rs.500 in bank a/c with kotak from which the money was going to be taken. I called vodafone on the 19th of Dec asking about the payment they said it will b taken on 20th dec 2009 and then again i called vodafone on the 21st dec 2009, they said that due to some reasons ecs is not going through , and they promised me that they wont charge me. I got a message from Kotak that my ECS got returned due to insufficient balance though i had balance on the 20th dec. Now today on 24th i came to know from kotak that vodafone took the payment on 17th 3 days before the payment due date. On calling Vodafone they said sorry for the wrong information given before but ECS is processed 3 days before payment due date..and now kotak charged me RS.220 for ECS bounce and Vodafone is charging me Rs.200 for ECS bounce.. So though its not my mistake i have to pay Rs.420 unecessarily due to sheer misguidance by vodafone.. This is completely unfair. Please advice what to do and what actions should i take. Thanks.
