Incompetence, product does not work and we are expected to pay.

We purchased an internet package with an uploading speed of 20 and downloading speed of 40. We pay R1050 a month and the uploading is on 0.3 we've tried everything. We can not do our work. The employee that came to install the fibre wanted to leave without checking if it worked, I ran the speed test and it wasn't even on 3 upload speed, i then called him back into the house where he continued to "link" it up. It still didn't meet our expectations, he then said we must phone him back if it doesn't work, he's ignoring my calls. We don't have working internet and we are expected to pay the R1050 plus an extra R1000 for installation before 6 July, our internet does not work, AND NOW WE HAVE A HUGE ISSUE BECAUSE WE NEED TO WORK URGENTLY. Yes we have data because we can't use our internet and yes we did take the modem in to telkom, apparently it wasn't good they configured it but nothing, it didn't make a difference. We must now potentially pay for a call out for something that never worked. The work ethic was poor, there were two gentleman, the one didn't really know what to do his supervisor gave him instruction while attending to personal calls on him mobile. He wasn't present at work.
