Waiting for a simple phone line for over 3 months

I moved homes and have asked Telkom to transfer my landline. The previous owners of my new house had a landline so this surely does not involve the creation of a brand new line. I've been waiting over 3 months and Telkom simply says they don't now when the line will be installed. How can one have to wait for so many months for such a basic service? It's absolutely ridiculous. Without a landline, I can't access the Internet, which means I can't work from home. What is one supposed to do in the 21st century without a phone line?
