@newtoitalldammit I have no idea what would happen if it is a fake certificate. Sorry.
We’re having a mare today as well. Had new fibre broadband installed this morning, inside is all good and the internet is working fine, but they have damaged the outside of our property in multiple places and our electrician is not at all happy with their cable management.
Not only is the wire run in a ridiculous way, apparently, the first time we get snow on the roof we’ll lose connection. The first lot of fitters had an argument with another fitter that turned up about the best place for the cable to be attached to, I went indoors and when I came out after they left discovered they have installed hooks in two places, including drilling through our new external render, but then not using that hook. The place they finally installed it has resulted in them cable clipping a black wire right down the front of our pale cream render, when it could easily have just run down the side, then leaving it to drape across a gutter and round the corner.
They installed the external box, then realised they didn’t have enough cable for it to work in that position, so moved it, leaving four drill holes in my brickwork, which they said they would fill, but didn’t.
They shattered a total of four bricks where they drilled into the side of the house for the attachment to the router, leaving them at risk of water ingress.
Finally, they left their packaging/litter on the driver under the installation and liberally scattered cable clip pins all up the side of the house and just left them there.
Oh and the second fitter that turned up insisted on cutting back the plants around the front of the bay window for ladder access, then cut down a mature Buddleja and just slung it across my drive, despite not actually using the hook he insisted needed to be installed via said ladder! 😡
