The Bangladesh Bank today asked banks to display their respective hotline number in a noticeable place in all branches and sub-branches such that customers can submit allegations to concerned authorities to resolve their problems.

Banks have also been instructed to display Bangladesh Bank's hotline number of 16236 in a similar way so that clients can submit their allegations to the central bank.

The hotline numbers will have to be tagged with the complaint boxes, which have been set by all banks, according to a BB notice issued today.

The banking regulator said telephonic communication is playing an important role in widening digital banking. Such type of communication is an effective channel to ensure improved banking and resolve complaints.

A BB official said banks will have to give more importance to improving telephonic communication so that clients can resolve their problems while taking banking services efficiently.

Under such a situation, the central bank issued the notice to boost telephonic communication.
