It dose say as they say, and every other other invoice has been sent to the correct email address, but this one was mistakenly sent to another department within the same company. The correct department does now have it but are refsuing to pay it based on the SLA that we have agreed to - but does their SLA count as law, or guidance. Is there anything in law that states we have a cetain amount of time to invoice a customer, or is it purely dicatated by the customers TnC's.
