All Pulse8 broadband is TalkTalk Business Wholesale. They do straight Openreach WLR3 if anyone wants just a landline. I have that from them.
Which exchange are you one? There aren't many without TalkTalk these days

The fact your phone works is good in a way, and bad in another. If it didn't, the broadband could still function in a very degraded way as you described, if one leg of the pair was connected but the other had become disconnected for one reason or another. (I forget whether it is the A or B leg that lets it work a bit).
As the phone does work, and the ISP's line test says it's fine, ummm
