Terrible service from technicians and call center

A few weeks ago i took a new contract with telkom. its a new land line and wifi. the package came with a wifi extender, new router and android tv box. i took a day off from work on monday the 22nd of January 2018. the technician calls me to say that telkom and no routers and he cannot do the installation. after me getting 3 sms's saying they have dispatched a technician to come out and install. i told the technician to come out and install cause i have my old router that he can use. but i still want the new router when they get stock because i am paying for it. he says to me that he is not responsible for that and i would have to pick it up. he finally gets to my house spends 5mins testing the line and says he has to go out and test the box. goes away for 45min comes back and says there's nothing he can do there is a underground cable problem. i asked to speak to he's manager. he says i cant if i want further information i must go the telkom yard and speak to the manager. i asked the name of the man i must speak to he says he doesnt know i must go there and see. till today i have no feed back on whats the way forward. today i call through. i wait on the line for 15minutes to even get to an agent. finally when i do i give the lady my details. she says please hold i hold for 5min and the whole time the line is dead. i had to cut the call and phone through again and still hold 13min again to get to and agent. now the new agents gives me feed back as they are still waiting for the cabling department to fix the problem. its such bad service from a multi billion rand company. i haven't got my line yet and that's the type of service i get. i am so ****ED OFF. cause how will i get a days leave again for them to come install when i don't even know when they going to fix the cable.
