Bharat Sanchar Nigam [BSNL] — prepaid mobile recharge wrongly

Address:

690554

Hi, my name is dinu and my mobile number is [protected], on dt-08/10/2018 at 2.30 pm, i have made recharge my phone by reload recharge application service on my number but by mistake he had recharges rs.399/- towards another number [protected], which seems same as my number, and the rs.399/- topup has been transfered to his number and he has denied to pay me. So, i have a request from bsnl (Government organigation) that in this situation what is the procedure to bring back any one money as this is against the law of conduct and justice. My request to government organisation to please make some more software for stopping such kind of mistake.
