Follow the wiring diagrams, only connections 2 and 5 required now, connection 3 is the telephone electro-mechanical bell wire that can cause interference to ADSL broadband.

At a guess, without pictures, blue/white and white/blue to orange and blue on the new cable.

Why have they touched your phone wiring?! Is the jointing box before or after you master socket?

When you say "old" and "new" colours, have the buildings installed new cabling?

well i finally managed to get back online after many trial & errors but now my speed is stuck at 19 when its should be 38 and up load should be 10 not 8. any suggestions

So this is an FTTC service?

What is the source of the figures? Actual connection speeds or results from speedtests?

if the modem was connected while they were fiddling, or when you tried to reconnect wiring, the automatic systems may have thought the line was unstable (which is sort of was) and have slowed things down to try and get something to work.

NOTE: If anyone is fiddling with the wiring it is always worth unplugging all broadband kit.

As previously requested, post some pictures of the 'damage'.
Without pictures, all you'll get is a 'best guess' and more DLM.

Don't forget, a picture is worth a thousand words!
