Ok, so here it now gets weird...
Having finally got hold of the magistrates department the original course was acknowledged as having been completed...
However although no points were to be issued the driving license was apparently to be sent to a Southend on Sea office although there was nothing on the online course to indicate that this was a requirement...
The original acknowledgement of the completed course has now been removed and the court case has reverted to being a non admission of a speeding offence (which was by definition of the course admitted), and now it it is an offence that is being prosecuted in line with my partner's income.
Which will be rather costly!
What a f****d up system !
