Vodafone India — Unwanted bills charged-3 consecutive mistakes

Event 1 : The mishap happened during my billing cycle from 28 Nov 2014 to 27 Dec 2015, during this period I was using a voice plan of monthly rental Rs.299 and Data plan for Rs455 ( 2GB) .When only 10 days were left out in this billing cycle I received a call from your customer care team that I have consumed my data plan so if I want they activate a 500 mb plan for the next 10 days and from the next billing cycle the older plan would get activated again. Because of this something happened which I missed and paid to much extra and notified the problem with your team on 16/2/2015 . The problem was that 500 MB which was earlier activated never got deactivated and I been charged on regular rates above 500 MB for the billing cycle for the billing cycle 28 Dec 2014 to 27 Jan 2015. The issue got resolved in the on 7th March 2015 and got a reversal of Rs.617 in my next bill cycle 28 Jan to 27 Feb 2015 Event 2 : Because of the event that happened as mentioned in Event 1 and which even your team never took the pain to indentify this system issue and the time taken by your team to resolve the issue I was again charged an extra during the billing cycle 28 Jan to 27 Feb 2015 and was charged an extra fee on my data usage in the similar fashion as it was done in case of Billing cycle 28Dec 2014 to 27 Jan 2015. I requested the reversal of this extra charged, your customer care team replied me back that this time I have to bear the pain . In fact the way your customer care behaved on the phone call seems like they are not interested in keeping me as customer ( check your call recordings).So at last I paid the elevated bill…because your people where not responding Event 3: Few days back I received by bill for the billing Cycle 28 Feb to 27 March 2015 as I was analyzing my through MyVodafone account online I found that no data plan is activated in not activated on my number .Secondly it stated that I have made some ISD calls of Rs.157 but don’t where I made those calls ( Need specific number on which I made those calls) . Thirdly the bill says that my Monthly charge is Rs.1799 ( which I think is the monthly rental ) I take this way because the bills also shows a USAGE CHARGE in another row…explain me this . Considering my Monthly charge I should have been charged Rs.754 ( Rs.299 for voice and 455 for data)
