No Telkom Line for 6 weeks

I have had no Telkom line for 6 weeks. I have reported the fault several times. Have at least 4 different reference numbers. Every time I a log a fault, it gets closed by Telkom without resolving the matter. There was a technician here once, according to him the problem is underground. The cable was damaged when fibre cable were put in for this area. I still get my Telkom invoices regularly. Why should I pay if there is no line and I have really done my best to report this. I am really desperate. I run my business from home and cannot make or receive calls from clients. If it was not for the business, I would just cancel the line but I cant because I need it for my employees and clients.
