Not fixing ADSL problem

Good day,

It's been about a month now that I struggle with my ADSL internet line at my house. My line goes off and on almost every 2 minutes, so I've logged a call with Telkom.

We made an appointment with a technician who phoned my wife, who would've been at my house on Saturday the 20th of January 2018. Surprise surprise, he never arrived. On Monday the 22nd another technician phoned to make an appointment in the afternoon, so I left work and headed home to be available for when he arrives and again no one pitches up. We've (both me and my wife) tried to phone the technician on the cell number he phoned us from but the line stays engaged till this very moment which is Tuesday the 23rd 18:20.

I took today off from work to make sure I'm available should they arrive but still no one came. And the best of it all is, if we phone the call center they just state that the call is already logged and a technician will phone us to make arrangements (and that is after my wife demanded to speak to a team leader).

I've never had to deal with such poor service in my life. I don't know what to do anymore to get this resolved.

I pay for a service that I can barely use, I had to use 3G to work from home which costs me extra money and I'm not getting any service from Telkom regarding this matter.
