How can this text if it's a landline?

It says "Service Provider"  and for me it is a local area call. We have a business, so I had to answer it. I got a recorded female voice saying " Hi! It's Tiffany! Did you know..." I ***g up. Then I went to use the line to make a call and the ****** "bot" was still rambling on! I finally had to unplug the phone to get it to disconnect! Then  I hit redial I got the lovely FAX tone blasted in my ear! I then tried to send a fax demanding they remove me from their calling list. I had to push the #9 to get it to it to go through, but then I got an error. Why do companies do this? Do they really think anyone would do business with them? I really hate this stuff, especially as a business owner. I can't just not answer calls that I don't recognize as I might lose customers.
