Pathetic service from zoom fibre

I recently signed up with zoom fibre and wish I had never accepted the marketing pamphlet handed to me initially. Installer came to my premises and installed the fibre cables exposed instead of burried like i requested. He said if the cable is burried it will not be according to the specs and insisted an exposed cable is the only way it can be installed. I had no choice but sign off on this as the installer guaranteed this is the only way to have the line connected. Now the cable inside my yard broke (could be by pets or even ******s that are always jumping in the yard) and zoom fibre refuse to repair it as they now say i am liable for this. I am with zoom for less than a month and have received the most pathetic service ..the so called area and network manager discussed my issue and want me to pay for something i did not break. I paid the months subscription and don't have a active line.
