Vodafone India — refund of the deposit amount

Address:	Bangalore, Karnataka, 560035

I travelled abroad for a week. Since i was new to vodafone they asked me to pay a deposit of 10000 rupees for activating international roaming mentioning that it will be deposited back to my account with 7 working days once am back to india and giving them a call. After coming back raised a request - request number :[protected]. The customer care representative promised that it will be refunded in 7 working days. After a week when i call back, they say it will take 30 to 45 days. The number of days is to ensure that they collect money and put it in some kind of investment?. And collect the profit and give us back. I think they need to be audited for the same. The transaction data can be used to do some analytics to see if they are doing something like this.
