Bank Of India — closure of deposit certificate

Address:

Hooghly, West Bengal

I had given rs 34000 deposit cerificate for closure on 9th april 2019. When i visited the bank today found only rs 10000 credited to my account. When i informed the staff, they told account is still active and rs 24000 still lying in my account. They failed to close the account and asked me to enquire after 1 5 days. Why should i wait so long to get my own money back. Please help to resolve the issue soon
