Deutsche Bank India — Lien amount generated even though I submitted closure of my account

Address:	Pune, Maharashtra, 411007
Website:	www.deutschebank.co.in

I have no balance in my account so I submitted account closure form at branch, but customer care forced me to hold and convert it into easy savings account (zero balance) but in the mean time bank sent bill of 1586, This is completely unprofessional way to take money from customer. When customer has already submitted the closure form why bank has kept on hold?
