I have Vodafone post paid connection, i want to migrate via MNP to idea prepaid, i applied for MNP and also paid all due bill amount to Vodafone. But due to system error at Vodafone, there was wrong due amount in my account and my MNP request rejected, i called customer care of Vodafone and then there was a waive off of wrong charges and said me to do all process again. So i have to do all process again, it all costed me a time and money.
