I have found an issue that if some has say £40 credit in their Terawallet account and they try to purchase £40 worth of products on the site.. When you select to pay with the Terawallet it does not hide the card details boxes.. It is still looking for the customer credit card even thou the amount to pay is zero. Now if I add 1p to the credit so its £40.01 and try to purchase the £40 items, it then gives two radio selections, one for Terawallet and the other for credit card payment. If you select Terawallet the card payment boxes disappear.
So it seems if the credit and items to purchase are the same value it gets stuck removing the other payment method. Is there anything I can change to fix this?
