I tried to activate national wide call rate 50ps offer(cost Rs.104) through www.ideacellular.com by internet banking(ICICI Bank), and the amount was deducted from my bank account . But i received a message to my mobile stating that the transaction has failed and the money will be reverted back in 7 working days and till now the money is not credited back. I called Customer care nearly 20 times and every time they give me a new deadline . My IDEA mobile number is [protected]
