Indian Overseas Bank — Service Tax challan

Address:

503020

Sir,
I have sent service tax for rs 84027 on 30/06/16 through narration cbec-300616-net @925536. But the amount neither credited to service tax department nor returned back to my account. Inspite of repeated complains to branch as well as internet banking division the result is null.
This is the last warning otherwise i may go to banking ombudsmen/rbi for the solution. Please look into the matter as soon as possible.

Thanking you,
