Nanks whenever dealing with banks you need to be pro-active - don't just accept what you read or might think appears in T & C's - the big 4 appear hungry for customers recently.
I previously held Altitude Black and then Westpac trundled out the 2 x pts offer for 3 mths for new customers. I called Westpac and asked would they give me 2 x pts on existing card for 3 mths and if not I would cancel and go get an ANZ Black Card.
Their response was we cannot give you 2 x pts with existing card - but apply again for new card and we will track progress - once new card issued we will roll existing balance into new card and cancel old - that way you will get the 2 x pts.
So might I suggest you just call ANZ and tell them you want to apply for new card and you expect the bonus pts and if they don't accommodate you tell them you are off to Westpac Black - again there is no down side - the worst they can say is no.
thanks for the advice
