I had a bad experience with 1-800-Battery. I booked the 11-1 pm time slot for a replacement battery at about 10:45 am. I waited but did not receive any calls or messages saying that they would be late. I called at 1 pm and they said the technician would be there in 45 mins. After 45 mins I called back and they didn't know where he was. He finally arrived at 2:45 pm but did NOT apologize or mention anything about the fact that he was 1 hour and 45 mins late. If I had known that they wouldn't be able to make it in the time slot I had booked I would have called another service because I had to leave for work at 3. Also, it wasn't great to get hit with an extra $25 travel fee right before checkout.
