Won't be paid a salary of Telkom doesn't wake up.

My girlfriend and I purchased a property in a building next door to where we staying now we move on the 1st September we have given over 30 days notice that our ADSL line needs to be moved. Telkom was suppose to organise a technician to see to the relocation they keep coming back that there is no technicians available due to faults. My girlfriend works from home and if there is no internet access they won't pay for the downtime. If this doesn't get sorted out she risks losing her salary and not being able to pay her share of the mortgage. It's a bad situation Telkom is creating.landline number is ********** 943
