Evri possible double tracking number

[leo-m94]

I may have made the mistake (Although, I dont think i did) of putting the same shipping label on 2 parcels.  Of course the parcels were for different people.  My question is would Evri know the same tracking number has been used on 2 different parcel on a different day?  And what happens?  The customer has his item he bought i posted on day one.  However I may have posted a different parcel to him using the same tracking number the very next day.  I would assume this should have flagged up an error?  Please help

Ok, if anyone else see's themselves in the same situation as I am.  The answer is yes.  Evri actually delivered the 2nd parcel on the next day using the same tracking number.  So have we found out a way to send parcel to the same person for free?  Why did they allow this to happen?  I don't know.  I just need to hope my 1st buyer will send me the parcel back.
