Don't bother, waste of time and money

I have never been able to access my business banking app to track my payments as it's important for me to process orders once payments are done. Every time I call in, I'm advised to try again later, the same thing the app tells me when I try to access it, I have tried multiple times to reset password but to no avail. Today I tried to purchase products for my business and the transactions declined despite having funds, then I received an sms notification to to say the transaction had gone through, but the shop said they had not received anything even showing me statements. I tried to call in twice, every time we get cut off, no one calls me back. I am still getting the same "unable to process transaction" message when I try to log in and track this payment
