Appalling service in fixing a fault

We have reported a fault on our landline 5 days ago. Customers try to ring us and we cannot hear the ringing. We are losing business daily. The ONLY WAY to report a fault is on Telkom's useless unresponsive website. We have received NO INFORMATION at all on why it is not fixed. We cannot get ANY RESPONSE from Telkom at all no matter what way we try. The online chat function appears to be disabled. What an appalling company Telkom is, what appalling customer service, how abysmal they are at helping customers. They do not deserve to be in business
