Bank app and internet banking

I’ve tried to do a payment on the app and on the internet online but every time the message came back saying “ could not process the payment try again”. I tried about 5 times with no success. Very frustrating! When i phoned the bank for help i only get the computer voices, and cannot get it resolved. To go into the bank is a nightmare. You have to have at least half a day, and its very frustrating.
