Landline and adsl

I have app**** for a landline and internet service on 23 July 2018. After fighting with Telkom for over a month, a technician finally came to my place on 7 September 2018 to install the line but pitches up with no router. After many calls to Telkom, their customer service agents keep telling me to wait. I can’t understand that Telkom being such a big telecommunications company does not have stock of a simple router. Now they telling me to go to their stores and look for a router. The service and incompetence of Telkom is just purely pathetic. I’ve given up hope. No one seems to be able to solve this issue.
