A balance change can look confusing even when the purchase itself appears correctly, so I’d first separate what the account shows as pending from what it lists as completed. I usually write down the transaction amount, purchase time, available balance before and later, and any wording shown beside the charge. That gives a cleaner timeline than saying the balance just looks different. If I wanted a clear explanation, opening Green Dot Corporation phone number with those numbers should keep the conversation focused on posting timing rather than a dispute. I’d also mention that nothing appears duplicated, since that narrows the question quickly.
