An acknowledgment email arrives within minutes of submitting, from Bumper (support@bumper.zendesk.com), subject "Your Request Has Been Received". It commits to a response within 45 days (extendable once by up to another 45 with written notice), says a privacy specialist will follow up within 10 days if they can't verify you from what you provided, and gives ccpa@bumper.com for questions. Save it. It's your proof of submission.
For the removal itself, the only documented figures for the system Bumper runs on come from the family's 2024 CPPA filing, made by BeenVerified, LLC, which reports a 3-day median and a 10-day mean across the deletion requests received that year. Check back after a couple of weeks, and if your record is still listed, email privacy@ltvco.com or ccpa@bumper.com referencing your original submission.
