No service after 28 days

I app**** for an ADSL line on 3 January 2018 for my home (online). 10 days later I had still heard nothing from Telkom so phoned them whereafter the lady did a manual order. I opted for the special that they were running in January. A Courier delivered my Range extender and LIT box but no Router. Last week a Gentleman from Open Serve came to install my line but could not complete the installation due to there not being a router. Yesterday a Gentleman from a different company came to install my router but the line was not working. Today I contacted him again to install the router as the line is back on but he refused saying that he did not install the line so he was not going to install the router. I have tried in vain to get hold of Telkom today. I have tried three times thus far holding on for 18:56 minutes then 14:13 Minutes and then 20:51 minutes. Nobody answers the phones. I am now extremely irritated and want an explanation for the pathetic service as well as my ADSL up and running.
