FTTP Good Practice

This query is about the way Openreach install underground connections.
I am in the process of getting FTTP installed by Openreach . It became available in the postcode last December but the necessary groundworks for some of my neighbours did not start until late April. The area is 1980s build with no ducting for the phone wires.
I have been given a connection date in July and a few days ago Openreach turned up unannounced to lay the fibre from the pavement to the front of the house. They brought a mini-digger and told me they had expected to dig up 30 metres of pavement but on arrival discovered this had been done by a contractor a couple of weeks before. (As an aside, the contractors cut through my phone connection in the pavement and they did the repair themselves !)
The Openreach guys did some work then sat in the vans for quite a while, and all I saw at the end was a coil of fibre against the wall of the house and the 'engineer' replacing a few blocks in a block-paved path. I didn't see any ducting and he said it was unnecessary. They want trough a couple of flower borders and several metres of lawn as well as the path.
It was only a day ago I found the fibre was not buried at any depth when weeding the border! Also, where it came from the pavement it goes round the edge of my driveway on the surface for about 20 cms.Whilst this is just into a border, it looks vulnerable.
The fibre is about 5mm in diameter and marked DEXGREEN 21 41/25 COF 256 FTTP CONNECTORISED OH DROP CABLE 25 Property of BT BN 161010.
Should I be complaining and trying to get the fibre buried deeper? Advice please.

I would be contacting whoever your ordered your FTTP from , tell them that Openreach have been to fit the buried lead on prior to the final install, and that it has been done in a very substandard fashion, which you wish to be rectified, and completed to an agreed fashion.

What you have there is a clear bodge. It ought to be in some form of ducting, and to the standard depth.

Whinge, moan, do what it needs to get it sorted. You could even email the Openreach CEO’s office …..
