They would deduct your balance without any notification and you wont even know unless you are in any emergency and your cellphone says the balance is 0 rs.Their galleries would be a small shop with a single guy who wouldnt help you in any way.If he would than he would charge you 50 60 rs.Call centers are full of people who do not know to speak properly.They would keep communicating within themselves about their daily chores and keep forwading your calls.If you want to waste your money than only give it a try.
