I would first like to understand [cash-collection service]. Must the full amount be collected at once, or is partial collection permitted? If it is, how does the receipt separately show the amount collected and the remainder, how can the remainder be checked later, and does the original collection deadline change? Please state clearly if partial collection is unavailable. This is a product enquiry, not an attempt to avoid limits or verification. I am not providing identity documents or collection credentials or giving transaction instructions.
