Speaking to whoever is in charge at the practice would be my first port of call as they can take measures to ensure it does not happen again, perhaps by amending their kitten worming policy. They should also bear the costs of any treatment that arises out of the mistake if they are shown to be at fault.
Reporting an error to the Royal College of Veterinary Surgeons at the outset will unlikely acheive anything other create bad feeling. However, if they refuse to aknowledge the error and it was clearly their fault then I would contact the RCVS to make a complaint.
I hope they continue to make a full recovery.
There is another thread about milbemax that would be worth you reading for more opinion on this wormer
