Not addressing the problem

I have been without internet for a week now and the first time I phoned to complain they said it would be addressed in 48 hours, and everyday since then I have been phoning and they keep giving a new reference number and saying to wait, but so far no technician has even come to my residence. This is also not the first time this has happened, previously I have had no internet for 3 months. I do NOT recommend getting ADSL because Telkom has a monopoly over the ADSL line business and if they don't address the issue there is nothing you can do, I instead recommend getting LTE from another ISP, it might be a bit more expensive, but at least you can have the option of switching if they provide bad service. Note: our ISP is Afrihost, but they are not at fault because the ADSL line is broken
