If they cant get your name right then the summons is obviously not for you - send it back 'Not known at this address' lol
Seriously take legal advice but I believe it should be thrown out by the judge, maybe entertaining to go as the Judge offen slags off the police for being incompetent and wasting court time ... always a pleasure to hear lol
P.S. If it is the same topic and related to the same question you can reply to your original question rather than starting a new thread
