Telkom incompetant

We ordered a swithboard from Telkom. Firstly it took for ever. Once received it did not function correctly and the Telkom staff Tshepi Mothoa promised that a techi will come and sort it out. We have emailed her as well as the sales person Leanne Josephs as well as reported it. All that happens is they sms us to say the adsl line has been repaired?????? I said the swithboard is not working again an sms comes to say the adsl line has been repaired. What dont they understand. Nine months later. We have begged for a manual so we can see if we can sort it out ourselves. Nothing. We now have an expensive switchboard that does not work correctly but we are also paying for advertising with Telkom. They are incapable of servicing products they sell you.
