Failed transactions

Love the progress the card is making but failed transactions needs tidying up.
While ago card failed on second use in a co-op on both contact and pin.
Money was taken and soon refunded, two comments:
1.Poor connection meant that another purchase occurred between spend and refund. There is only colour, black and dark green to distinguish them. A credit to my account needs to be made clearer, perhaps with words.
2. the failed transaction was still noted in the stats and counted in my average spend. Both debit and credit have now gone from my time line but the number of transactions and average spend are still incorrect.

Cheers
