Did you leave an alternative number for the engineer to ring, i.e.: your mobile phone ??
I'm not justifying what
may have gone on with your visit, as it is bang out of order if you've been the victim of a 'Can't be arsed' engineer. However, I can tell you from personal experience that on quite a few occasions over the years, no amount of banging on the door or ringing the landline resulted in the EU giving access.
"I was in the garden", "I don't answer numbers I don't know", "I just nipped out" ……….. are excuses given
if I manage to get them on their mobile number.
The only other issue could be the EU being a proper oining sod ?. I've done it myself with an EU on my own patch. He was konrado's cousin, I'm sure ??
. Before anyone jumps down my throat, there's a heck of a lot of history to that particular EU's story.
To sum up though, it does appear on the face of it your line-length may have put a feint-hearted engineer off attending. Especially if he's on a 'Performance Plan' for low productivity. He could be a world-class engineer, but that means jack in todays BT. More prod, more prod ….. is the mantra.
