Did he actually say that?
BT themselves don't do the customer facing work, it's done by Openreach or an Openreach subcontractor. Typically you get much better results from an Openreach engineer than a Kellys or Quinn engineer - they're generally hopeless.
He did, but I'm guessing it could be more likely Quinn based on the appearance, hard to say since there was no labels or anything on the van. He probably thought that because the guy had a spare BT Hub, and apparently OR engineers aren't allowed to carry those any more.
Either way glad it's a proper OR engineer this time and seems to have solved the issue.
