You should not be getting this. What number is this? Is your bank trying to ring you? Check your settings to see whether it has to do with how you have set your phone up. Banks do not normally ring showing their number, so do you have your phone set to not accept phone calls from unknown numbers, as you would then have to make sure that you allow phone calls from people and companies whose numbers do not show. Make sure you have not blocked them, if number is showing, as that will stop you receiving calls.
