Been connected now for 4 days and the speeds arent as advertised.

only getting an 8-9mb download. called O2 who advised the setup at their end is fine and to wait up to 2 weeks until the line check is complete to get an accurate measure.
got an email in the morning stating:
Just a note to say that we've completed a health check on the actual speed of your O2 Home Broadband line. Unfortunately it's not as fast as we hoped it would be when you ordered - as your BT line can only support.
Should I take this at face value or ask them to reset my profile or start looking for another ISP?
