Transactions in Agrani Bank remained closed on Sunday due to power outage and server problems.
The bank's head office in the capital's Motijheel faced the power cut owing to problems in the underground electric line of the office early on the day.
Though officials of the bank's head office claimed that transactions took place, officials concerned of the principal branch said transactions had been closed since Sunday morning and there was no possibility of resuming it on that day.
Some officials in several branches of Dhaka district told The Business Standard that no transaction took place there on Sunday.
An official at a branch in Sylhet said they had been sitting idle since morning as they could not make any transaction. Customers had to go back, he added.
Another official of Agrani Bank, seeking anonymity, said normal transactions could not be made in several branches, which run under his supervision.
The Internet connection was disrupted due to the power outage, said the officer.
According to an official, server problems are their main concern rather than the power glitch.
He alleged that the bank authorities did not pay any attention to the server problems, which started before Ramadan.
Mohammad Shams-Ul-Islam, managing director and CEO of Agrani Bank, blaming the Dhaka Power Distribution Company (DPDC) for Sunday's power outage, said, "How can a commercially important area be left without electricity for so long?"
He said a generator at the head office ran for hours but it was not possible to run the generator further. So they hired mobile generators later.
They were trying to fix the problems, he said.
Bikash Dewan, managing director of DPDC, told The Business Standard that they were trying to find out the problem in the underground electric line.
He could not say how long it would take to sort out the problem.
So they were trying to provide electricity to the bank's head office from another line in the area, he said.
