Reserve Bank Of India [RBI] — non-refund/credit o[censored]nauthorized transaction

Address:

A.P State Council for Science & Technology, Moung Phii complex, ESS sector, Arunachal Pradesh, 791111

I am an savings account holder of vijaya bank, itanagar, arunachal pradesh. Inspite of my repeated complaints both in the city branch vijaya bank, itanagar and also in its customer grievances website (Complaint grievances i'd pgrs[protected], pgrs[protected], pgrs[protected] etc) but still no action has been taken. On the morning of 24/12/2018, i received a message that an amount of rs14, 784 was deducted from my savings account [protected] with the details shown as cwrv/602290/270218/papumpar/ru. This transaction was not done by me. So i made a complaint at the city branch and online too. But it's more than five months now but the said amount of rs 14, 784 has still not been credited to my savings account inspite of the online status of my complain showing the status as resolved.
Please verify and help me get the amount credited back to my savings account which was not initiated by me.
