Sorry couldn't find a .2 star so I hit 1 star. The installer installed a battery on my BMW that made it shut down completely, after I demanded he fix the problem the tech advised he was calling his support but actually called the police. The police told him he was an idot for wasting there time, apparently these techs have no supervisor or help after 5pm so they panic when they have an issue. My vehicle is now broken and BNW has no idea what has happened to my car, after calling the 800# and asking for a call back Chris and his company have refused to respond, but instead have now charged me $112 for there tech coming out breaking my car taking the battery he installed put and putting my battery back in. Despite putting my old battery back my vehicle still has major electrical problems and is currently not working, can't believe they charged me for not doing the only thing they advertise they do right.You guys are crooks and will have to be shut down to learn a lesson
