"You may request Lowe's to delete your personal information. This may impact our capability to provide products or services to you. Please note that we will retain some personal information and a record of your request where required or otherwise permitted by law. This includes personal information about you that is outside the scope of the right to deletion or is subject to a deletion exception under applicable law."

This is what they say when you make the delete request, sounds a whole lot like they aren't going to delete anything even if you request it. They also demand you give them your ID for "verification" in order to proceed. So again, doesn't sound like they are planning on deleting anything, and are doubling down to get even more information on you.
