No phone lines for 3 weeks - NO Help

Good Day, Please can you help. We have had no phone lines for +3weeks. Every time we call Telkom we get a new reference number but the problem isn't being resolved. We have 7 lines with Telkom, our debits have went off despite us having no lines. A technician was sent out and said we must contact Nashua to sort out cords and it will work. We contact Nashua and were charged a heavty call out fee and still no lines. The call centre agents are an absolutely joke seeing that no one can help. We are loosing business because of this and I think it is pathetic service from a well reputable company such as Telkom. When asked to speak to a supervisor or manager, none off them are available? How is that possible?? hOW CAN A QUERY BE CLOSED WITHOUT BEING RESOLVED? <br> <br> Reference numbers:<br> 256CNK211015<br> 47CNZ221015<br> 318CNZ261015<br> 64CNZ101115<br> 779874<br> <br> <br> Please can someone contact us urgently to get this matter resolved.
