Inaccurate website Connection Availability Check

We recently bought a house, thinking that we will have access to a Telkom ADSL line, since that is what their website says. Went to an Telkom shop, payed the connection fees, and waited weeks for the technician to come and install our line. When the technician arrived, he told us that the line probably just shows active on the website, but it definitely is not, and cannot be activated again. We will have to pay a huge sum of money to get new lines to our address. We work from home, and we are heavily reliant on Internet access, but now we bought a house, trusting this ridiculous company's website that we will have connectivity. Wish some other company could do what they do - it won't be difficult to do it better.
