Paytm Mobile Solutions — Can't login

Address: Thiruvananthapuram, Kerala, 695001

Sir
I very recently installed paytm. I transferred some money in the wallet and started doing transactions. It was ok. But 3 days back i put Rs. 1000 in my wallet and made a paymentof around 475. But from next day thae remaining amount is missing from my wallet. A person transferred Rs. 5000 twice to my wallet. The amt got debited from his bank account. I received an sms stating tht my wallet has been credited with Rs. 10000. But when i check no amount is there.
In the meanwhile i tried to generate the bar code but i couldnt do it. So i uninstalled the app and then re installed. But now i am not even able to login. Error message is coming saying that the same mobile number is with another account. This is my personal mobile number.
Pls guide me as soon as possible as i am not able to take the money i received.

Regards
Deepak Bhass
