I had a chat to bank rewards today,and queried why I got paid less miles that what I calculated, so it seems when they did payout yesterday for last months purchase they paid out based on what my current% shows in the app and not what it showed last month% ,which she agreed is not right, for eg i saw in June I was getting 75% back, now in July it shows 55% so when they paid me out for July they gave it to me at 55% not at 75%,unless it as a mistake,or that's how things have been which I doubt, she will follow up and get back to me
