Broadband speed dropped, call centre of no help

Question

Moved into a property in December which had an existing BT line and had had BT broadband.
Throughout December and January I've had about 5Mbps speed.
Had recently noticed the speed had been significantly slower and two days ago I got round to checking and looking into it.
On testing (using BT speedtester) it showed a 0.5Mbps speed.
I phoned the BT technical support and was promised (specifically so as I queried the assurance) that I would be back to 5Mbps 'within 24 hours'.
24 hours later it was still showing 0.5Mbps. Phoning again I had to go through all of the same steps and have now been told I will be back to 5Mbps in 48 hours. Except the callback I got then told me 1-1.5 Mbps.
Obviously the initial promise wasn't followed up on but irrespective of that, 1.5 when I live a few hundred metres from the exchange is less than acceptable, especially when I've had 5Mb speed in the past.
Testing using bt speedtest shows:
 Download speedachieved during the test was - 1.25 Mbps
 For your connection, the acceptable range of speeds is 400 Kbps-2 Mbps.
 Additional Information:
 Your DSL Connection Rate :7.42 Mbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 1.25 Mbps
The OP profile and 'acceptable range of speeds' are way down on what I had at the time the line was set up and throughout December and January.

It's not connected to the master socket and I can't connect anything to the master, or do anything with it as it's (bafflingly) installed in the attic (which isn't boarded).

Answer 1

if you are already with a low profile then the next restart then starts the reset time again this is why it is important to maintain a stable connection once the profile has risen to its correct level then just one reboot now ant then wiull have no effect on your profile
