If someone doesn’t have internet, how would they read a reply? The only phone service I have is my home phone. I did have a cell phone 1989 to 1995, I needed it to get my work call as a over the road trucker for a nationwide company. They would not allow pagers or answering machines or voicemail. I gave it away the day I left that company.
I get an email every 6 months for oil change. car oil minder said 10 mo since we didn’t drive a lot. Does dealer keep track of that 10 mo figure? Nope, got another email at 6 month interval.
