NO TELEPHONE LINES FOR 3 WEEKS AND NO HELP

We as ENM Trading are disgusted in how Telkom treats their customers. We have not been able to make outgoing calls or receive calls for over 3 weeks. This is a company and we are losing revenue because of this problem. We have been to the Rosebank shop and have dealt with Kabelo on numerous occasions and still no luck. There is no feedback at all from Telkom, or assistance in any form. I held on the phone with Telkom for 4 hours on Thursday and again for 2 hours on Friday, with no solution. I get told to phone Kabelo, but the number I keep getting from Telkom just rings and rings. I have also sent 4 emails to the escalating department, and again no feedback. Does anyone know how we can contact a director in Telkom as this is absolutely not the way that companies or for that matter anyone should be treated? The switchboard has 3 lines, one being: ***. Let's see if anything transpires
