Technical issues on Internet Banking

Our business has reported a technical issues with online fine payments on 2017/09/04. Up until now, NO SOLUTION. I have contacted the Complaints Resolution Center on 2017/10/11, where they have promised a 2 hour turnaround time. Today, when I followed up on the issue, I was told the turnaround time is now 3 to 5 business days. This delay technique has been going on for more than a month, ask a question via e-mail, I answer IMMEDIATELY, then I get another question 4 days later. I am REALLY considering to move our account. Any suggestions for good, but affordable business banking?
