I set a time between 8 and 10 AM online. My car was in a parking lot so I had to borrow a car to get there. I waited for two hours and never got a call or text. I had to call back 1800batterey and was told the technician didn't come to work?! There was no explanation as to why I was not contacted. I had to wait another 45 minutes for a callback and was told a technician would be there in an hour. this time I did receive tracking software so I knew the time of arrival. That technician did change my battery but had some issues with the terminals. The car started and I dove to get the car I borrowed returned and when iI stopped the car it would not start again. It turned out that the terminal needed to be replaced. Requiring me to borrow another car to get the part and replace it. All totaled, it took 7 hours. When I signed up for the service I thought it would be a convenience but it ended to be a major disappointment for the money. I should have changed the battery myself and saved the cost that was charged.
