Customer Portal never working when updating details

<p>A few months ago I logged into the Customer portal to change my bank details and when you click on submit, a "wheel" just keeps on turning and turning and the bank details never gets updated, so I emailed my new bank details to ********** which I never got a reply to. So I complained on Hello Peter and my bank details were updated. Guess what? The Customer Portal still doesn't work as it should. I want to change my bank details again, but when I click on submit, the "wheel" just keeps on turning and turning and nothing happens. When I submit a ticket from the customer portal, I also just get a huge programming error and the ticket isn't send. So whoever created the website, clearly doesn't know what he or she is doing. Please get someone from Bytes to test the consumer portal and fix it and please get someone to contact me to update my bank details. Thank you.</p>
