If they contact the same carrier during external investigations wouldn't there be a problem if the carrier notices multiple refunds at the same address?

In terms of the DNA, that's what you'd need to monitor.

The same carrier servicing many deliveries In succession and In close timing, Is on the same principle as hitting the same company with one SE after another. It's likely to raise suspicion.

So if I've just done a refund with a store that did an investigation should I wait before hitting a different store?

They're obviously not related so In that respect, evidently It's not an Issue.

Was the DNA used?
