I was charged twice for one bill and was told it will be refunded in 24 hours. After 24 hours I emailed to center head and was told to submit the deduction sms and bill images, after submitting this I was called by CCD Area Manager now he is asking me to wait for 7 days and submit my bank statements. My complaint is against CCD that due to their faulty machines I paid double amount of money and now instead of apologizing and refunding they are asking me for my bank statements. I want my money to be refunded with in 7 days, as I faced this problem on 4th and today is 3rd day.
