Paytm Mobile Solutions — Money deduction from bank account

Address: Katihar, Bihar, 854105

Dear sir/madam . I added 5000 rs on my paytm wallet on December 24 2016. And it was failed even then money was deducted from my account. And they said that they would refund the money back in 2 days but still I did not get it back . And now my bank says that they had deducted the money but paytm claims that they did not receive it . Please help me.
