I am having this same issue with my westpac card - apparently I cannot link bank feeds for my personal credit card anymore (it was working until card was replaced) Unless I get a business credit card which is out of the question.
Even worse - MYOB wont let me import the statements manually!!! Keeps saying "The bank statement file cannot be imported" when I try to import the QIF or OFX so, unless I want to enter everything manually, I guess I need to switch to Xero (I'm THAT annoyed).
Also, MYOB cannot be phoned after 3pm in WA either so no help there. Not sure why I pay the monthly fee when I can't even get support
