Tata Docomo — Tata Docomo are the cheaters

I have tried to recharge the docomo sim card of my mobile for Rs.57 online. But instead of recharging it, they deducted my completed and also did not did the recharge of the mobile. Also many times they deduct many amounts from the mobile without intimating the customer. Hence when i tried to contact the customer service centre, then the customer care people do not reply and speak with every customers in a very abused manner.
