Got paper work from VRV

Got all my paper work from VRV on the 29th May .Was told to take it to the Canadian Embassy in London so I drove to London on the 30th May parked in Richmond car park went to the train station at Richmond to catch a tube train in to London. I walked from the station to the Embassy joined a very long queue only to be told that all work permits have to be sent in the post so what a waste of time and money that was.
