I would have given zero stars if I could have done. What an appalling experience. BP customer 'service' is entirely lacking. Even the complaints department had to be chased by Zoom (Renault's sourcing partners) twice before they bothered to reply. Fifteen emails to three different BP email addresses and not a single reply, not one! So the suppport is entirely lacking, the app is dreadful (read the reviews on the apple store!), and the time it took to actually get the unit installed was laughable. BP should be ashamed of themselves and get out of this market. If they’re incapable of diversifying, they don’t deserve to survive! Renault are now sensibly looking into the wisdom of continuing to use these jokers. The only positive aspect of the whole sorry mess was the freelance technician who came on time (once I’d finally got an appointment!) to install the unit, and was very helpful and informative. Otherwise, beware BP, they’re appalling people to deal with!
