Axis Bank — closure of home loan

Address:

Ahmedabad, Gujarat, 382350

For home loan closure, we required closure report, for that we have to wait for 5 working days, after that
We pay our home loan, but bank is required 9 working days to clear loan and 15 working days to return our documents.
Almost 1 month to clear home loan.
Up to closure report we have to pay interest.
And after full payment, bank will not response to us.. They only say that "plz wait sir, process will be completed up to given time period". If our money reach to bank then why bank delay process???
