PLEASE ADVISE, WHAT CAN I DO MORE!!!!!!??????

I app**** for ADSL last year 27/10/2017. At first the service was actually fast and excellent, however after they find out that there is no line connected to my house, things started to tumble down. It took them 7 months to find the connection point to my house to supply me with new cable. The cable was supp**** and routed by myself on the 04/06/2018. Since then I struggle to get them to update my order number on TELKOM's system. When I get hold of Telkom, on this number 10213, they said that they can't find my order number on the system, its is still with OPEN SERVE. When I phone Open Serve they said that it is updated. Up to now I'm still sit with no answerers and still no internet. It is almost a year!!!! The cable is in position and all that must happen is that it must be connected at the connection point and the router or modem mast be installed in my house. My order number for the ADSL are 357907
