Vodafone — incorrect billing leading to losses

Hi
I am appalled by vodafone’s behavior regarding my bill payment. The bill for sep 25 was outstanding and I had already written 3 complaint mails to the customer care citing discrepancy in my bill and that being the reason for me not paying the bill. I have had this connection for nearly 4 years now and all bills have been previously cleared. I had asked for a phone call from Vodafone representative to discuss this since the problem was at vodafone’s end and not mine. Vodafone for several months has been charging me with fixed plans which I had not taken. When this was pointed out a portion of bill was reversed in September but that was not enough. I am paying my bills since this is my only number in use and is a corporate connection and barring of outgoing has led to significant problems for me. This is however totally unacceptable.
On the 14th of October while I was traveling to Kolkata on business meeting (This is a corporate connection and only phone that I use) at aroung 5 in the evening after I attended a meeting and was waiting to get into another one I realized that my outgoing had been blocked without any notice to me. I had to call my car and there was no avenue for me to do this. I had to walk 2Km and waste 45 minutes to find a PCO to contact my driver and ultimately cancel my next meeting which has led to monetary loss as well as left a constraint on the relationship with the client. On asking Vodafone why this has been done the answer given was this is our procedure and I can complaint to whomsoever it concerns regarding this reckless behavior
I have also noticed that my plan continues to be on a per minute billing despite me asking the Vodafone to change this to per second billing as per current conditions. This has still not taken effect.
