The capital was in crisis of cash from ATM machines throughout the city due to "security reasons" amidst blocakde.
The main opposition have been waging agitation programmes throughout October and November demanding polls in line with their demand.
Both institutions use Group 4 Security services to carry out their refill at machines.
Dhaka Tribune contacted Dutch-Bangla Bank Limited, holder of the maximum number of ATM booths across the country, and BRAC Bank Limited over the matter.
A Public Relations Officer of Dutch-Bangla Bank Limited said told the Dhaka Tribune on condition of anonymity that Group 4 was refusing to refill the machines afraid of their own security.
“We have at least 700 booths in Dhaka. But it seems that this problem will continue as long as a political unrest exists,” he said.
Another official, seeking anonymity said out of the 3.1m debit card users across the country, 50% of them are in Dhaka.
He added some 40,000 credit card users are there in the country and out which 80% are from the capital.
BRAC Bank Limited Managing Director Syed Mahbubur Rahman said his institution was facing similar problems.
“We have about 200 booths in Dhaka. But the security forces are not willing to risk their lives during this blockade programme,” he said. “We are trying to address this problem and maintain customer satisfaction.”
The polls-related violence have killed about 100 people through October and November. Scores of others have been hurt, some with formidable injuries.
