1-800-Battery gave me a time slot for a battery delivery and replacement and never showed up. They also never notified me; when I called I was told that they'd reach out to a tech and call me back asap. Several hours later, I had to call back and was told that they realized no techs were available. A good rule of thumb is if you're going to no-show a customer (especially after telling them you'd reach out soon), at least let them know so they can make other plans. I haven't checked to see whether I was charged for this service, but thanks for the reminder. I'll be sure to leave my feedback on third-party review sites as well.
