New service, v. slow (almost nothing)

[#1]

Hi. My service went live on Thursday and was fine for the first two days (until Friday evening). From Saturday morning, it has been extremely slow, unusable. Too slow to properly load a speed test page.

I have tried multiple devices, both on wifi and plugged into the router. No differences. Router is plugged directly into the master socket and all that.

Phone/dialtone sounds normal, not the clearest but it never has been over the years.

The switchover was delayed and we were without internet for 22 days, so keen to get it up and running.

Many thanks,

@Jp12rfl Together with our network partners at Openreach we are prioritising customers who don’t have a phone line or broadband connection, meaning there might be a delay in Speed Faults being fixed. In the meantime, please raise your speed fault online at http://faults.plus.net.

Thanks - I've done that, but I'm not convinced things get sorted unless prompted directly - it took me three or four phone calls to get each step of my order moving, nothing happened until I specifically prompted it, literally every step of the way. That's not just plusnet, every ISP is like that really. But, still, waiting just means your case is ignored indefinitely.

I see some threads here have received line checks and whatnot, could someone do that on here? 99% likely to be a "flip a switch" fix at PlusNet's end, seeing as I had years of perfect service previously and this has happened just after changing, right?

Thanks,
