What is your actual Downstream Line Rates, up and down ?
If you weren't previously getting very close to 40, then the boost is highly unlikely to make any difference.
Postcode checks are too general and you would have been given an estimated range and minimum guaranteed speed for YOUR line.
What were those ?
Apologies for the delay.
Your line is currently in sync at 32mb.
I'm just sending you a Private Message to confirm some details so we can check the predicted speed range for your line.
Thanks for confirming your details. The predicted speed range for your line is showing between 52.4 and 32mb, with a guaranteed minimum speed of 29.8mb.
Your current sync speed is within the predicted range for your line.
