Preventive repair

We've reported this problem numerous times over a period of months, but no joy. Telkom installed a new line (new business property, so new poles, wires, and cables). The overhead cable became unhooked and is now laying on the ground. Trucks and other vehicles are driving over it, and it is just a matter of time before it is damaged or ******. Do we have to wait until the phone stops working, report it out of order, try to run the business without a phone for a few days/weeks until they repair it? ********** 597
