Is this change across all ANZ cards?
We have the ANZ Frequent Flyer and were recently offered to add an Amex companion card... no extra cost, just unlimited points earning potential (visa card capped for firs $1500 per month).
Anyhow, I told them I was happy with the one-for-one points on the visa and didn't want to spoil that by adding the amex or anything. He assured me all it would do is add the extra points potential and the visa earn rate would stay the same! He said to reply via sms which I was going to do over the weekend?
