Giving me sleepless nights

Only 3 weeks in and I already have so much regret :( They call me twice a day, the most annoying being in the middle of the night, with a false alarm about my battery because my car goes into sleep mode. I've logged calls (phone/email) about this apparent glitch but I'm yet to hear from a technician. And yet they were very efficient and readily available when signing me up for this headache
