2 months & 3 days landline not working

when I reported that my landline was not working on the 4 December I made it clear that there was no one at home during the day! I told the call center agent that Telkom needed to make arrangements for a saterday m y day off. Two months or so before this ,Telkom came on a saterday to repair my line. However this time round they would call in morning during week to say they were there to repair line. I was at work & couldn't leave. So arrangements were made for the saterday. They never showed . This has been going on like this for 2months. Telkom makes arrangements i wait they don't show up! What poor service!!!! My parents are in their 80's & they live alone overseas. The landline is the only way we communicate. It's cost me over a R 1000 up to date using my mobile to check up on them.
