I made a terrible mistake when I once filled out an online form inquiring about auto insurance quotes. Immediately, we were bombarded with ads, mails, letters, brochures, invitations, quotes and phone calls from telemarketers. At first, it was just fine since we asked for it anyway. But it’s just annoying when people don’t take NO for an answer. We weighed the pros and cons and we made a decision so there's really no need to send in more offers and quotes. It's just a waste of time, effort, and paper, hehe! But anyway, that's how they sustain their business. I'm just glad that we can block unwanted calls and paper ads go straight to the garbage without even opening them.
