What are the risks of sending cash money transfer as a payment for a service?

We are a money sending business and that means it is our responsibility to move the money from point A to point B (transfer funds from a sender to a receiver). When using our services, we advise that you take caution when sending money to strangers. It is the sender's responsibility to know the party to which the funds are being sent. Paying money into our bank for a client reference number is the same as sending cash to a person, once completed it is irreversible.
