There is something wrong there as the profile should never start from 500. Were you on a 512kbps connection before?
If it doesn't rise by tomorrow morning then you will need to get onto them. Unfortunately unless you are very lucky they will refuse to do anything till after 10 days from the regrade
Get back to us if that happens. There are people here who have contacts, and we can ask them if they can help.
As 5km said, that is a great line. You will get a 7150kbps profile once it is sorted.
