Gordan and Gotch return week problem

I has been reported that customers who have sent their week 15 (last weeks) returns to Gotch, have received an email confirming the returns. Now that they are sending their week 16 returns, they have had week 15 marked as not sent.

It appears that Gordan and Gotch has resent the week 15 returns form last Thursday. This has reset the sent status on the list of returns forms.

My advice is to notify Gordan and Gotch to fix the problem and in the meantime ignore the unsent returns form.
