I’m vodafone customer for so long but i’m disappointed by there service. I have converted my number from postpaid to prepaid and at that time i have deposited my last month bill in cash and the same has been deducted from my account too. Your executive said it will automatically credit in my prepaid balance with in 7 days but i haven’t received yet. Kindly resolve otherwise i have to switch to other reliable network
