Untheorized browser

I went to the Quagga branch 3 times since Thursday trying to get help from Business Enterprise online. I spoke to 9 different consultants and 5 hung up the phone on my ear the branch manager witness is. I can't access my online banking because it cannot recognize the browser, I went through every step they said I must do, and even the branch manager assisted but failed, we requested to escalate the matter but neither of them assisted us, I am stuck as we need to pay people their salaries, Can you assist urgently so. I am so frustrated.
