That's entirely her fault.
Firstly for getting caught speeding, and secondly for failing to notify the DVLA of a change of address as she is legally obliged to do.
Happens fairly regularly. If you don't receive notification from the DVLA of points because you've moved and haven't told them...
My photocard expired this month. The DVLA sent me the renewal notice in June, whereby (on a Wednesday afternoon) I took my completed form to the Post Office, who stamped it, took a new photo, and sent it off.
My new photocard arrived in the post on the Friday morning, less than 48 hours later...
