@Nosey Parker, as a matter of interest, if a non-PoFA compliant NtK is sent within the relevant period but then a second, amended and PoFA compliant NtK is then sent out, again, within the relevant period, which NtK would take precedence, as far as any subsequent legal action against the defendant as keeper, is concerned.
Is the operator able to simply claim the the second NtK is an amended invoice?
