On a recent call out on the M62 The lights were on as the car was on the hard shoulder. When he loaded the car the lights were still on as it was dark. I did not travel with the vehicle as he called me an ambulance as I was unwell. I did provide my home address. The lights were left on after unloading as were still on when retrieving the car 3 days later hence flat battery requiring replacement. In view of this I find the negligence unacceptable and this has cost me money for the replacement. I also am dismayed regarding the additional detail and confusion regarding the whereabouts of the car and keys.
