Warranty issues

Following delay after delay  ( not my fault ) we finally made it to MCC and a reasonably amicable meeting with Eddie and Marion regarding Tardis Two's ongoing ( since it was built in 2013 ) electrical faults. We got the impression we were distinctly unwelcome. We made it crystal clear we want the problem solved within the warranty period, once and for all. After all, they have had four attempts at it over 3 years. If they fail this time we'll get Trading Standards and/ or small claims court on board ( oops, that same old pun keeps rising to the surface, sorry ).
