Have a look at uno
. A smaller ISP with possibly the best customer care/service and a huge reputation amongst the regulars here.
The owner also posts frequently
here. (Search for uno
setting it to search for username for the last 6 months).
There are three of four people on these forums who rail against them as they are unable to migrate to them, (uno's order system says "No"), and one who was previously with them but can't get back. AIUI quite a few Origin users who were having lots of congestion there have moved to uno recently.
Having suggested them however, it seems very probable your line has a significant problem which any ISP could have trouble getting Openreach to sort out. At least you are likely to get the efforts made.

If you never think of anything off the wall, you'll never think of anything original.
