No, you may not roll two payments into one, single refund. For example, if you received two separate payments of $500.00 each, you may not process a single refund of $1,000.00. You must process two refunds for $500.00 each.
NOTE: When a refund is processed, BrightSide must reference an incoming payment. This security measure is in place to prevent someone from issuing a refund to a card which was not used to make a payment. It also helps reduce fraud by preventing illicit refunds.
