160kbps for last 6 days...

@MinusNet2112  I'm sorry that no one got back to you so apologies for the delay.
Your fault is in an awaiting appointment status at present as there's a requirement for an engineer visit., a voice mail was left for you this morning. Please check the ticket for full details and respond there if you can please. I will ask a faults agent to give you another call to be on the safe side.
FYI engineer visits are available in the following slot times between Monday and Friday.
08:00 - 13:00
13:00 - 18:00

I have cancelled the call. I already have had the wiring checked, albeit independantly. This was stated previously in my call. I'm just totally fed up with the whole thing, and cannot see what the engineer would do at my home that hasn't already been checked. The IP profile is 3000mbps for the past two days and has stayed there. I have turned the router off this morning to see what random speed it picks up later today - or may well retain its profile - who knows?
BT Openreach vans have been seen around my street working on the roadside boxes this week. It is (surely) an issue with Wholesale and at the BT exchange?

I'm intrigued as to how you've had the line checked independently?  BT engineers will run all sorts of tests on the entire line from your master socket back to the exchange, to determine the cause of the fault which could be dry/corroded joints hundreds (or thousands) of metres from your premises.  They also have access to specialist test equipment which can highlight these sorts of issues. 
Isolating your internal wiring is only one step of the fault finding procedure.  If you have an intermittent line (and getting a 135Kbps profile is a pretty good indication of that) then you will be taking your problem with you to your new ISP.

Barry,
It was a BT engineer doing a homer....a handy person to know.
Also, the fault only appeared after I switched off the router and went on holiday for a week. It had been running perfectly fine up until this point!
I know how the painful system of fault isolation and resolution works with good old BT, I deal with them through work.
If a fault (which is still open to debate) is still there when I transfer, I'm pretty sure it will be dealt with a bit quicker. Days of silence - why do I have to update a forum before I get a response on my Support Ticket?
I'm still waiting for an official response as to why going away for a week causes such an enormous drop in speed/profile. Again - the service was perfectly fine up until then.

Unfortunately we can't retrospectively investigate as to what caused a problem, unless it's obvious like a poor joint that an engineer finds.
As you've closed your faults ticket, there's little further that we can do but please let us know if you'd like to open a new fault so that we can actually fix this for you.
