landline not working for 2 weeks and counting

I have been experiencing issues with my landline for a little over 2 weeks. The issue has been logged with Telkom but still not resolved. Only promises that a technician will be sent out.

What annoys me most is that i have spent quite a lot on airtime making calls that would have otherwise been made using my landline, as well as on calls to Telkom.

I have never defaulted on my payment but I am certain that if i did, my line would have been cut immediately... So what happens when i am paying for a service that I am not getting?
