"Nothing 'went wrong' with the vehicle. I was collected by a Tesla model S (having upgraded from the originally requested Mercedes E-Class) but the booking still showed the Mercedes. I had to chase this up and correspondance ended abruptly with no confirmation that this had been ammended.
I also had to clarify the pickup address as the automated system did not list my pickup location. I ammend the booking with a note, spoke to an advisor and replied to an email, providing this imformation. Despite this I still received a phone call shortly before pickup asking me to clarify the location."
