Telkom lets you down again

I'm desparately trying to get internet connection on an existing fibre line. After application a technician arrived on Monday 7 October, only to be told that due to the call centre typing in the wrong street number (we did supply correct info) they could not do the installation. The whole process had to be repeated only to hear after follow up that they typed in the wrong unit number, despite the technician taking a photo of the address. On Thursday 10 Oct I was informed that installation would be today but after calling to confirm, we are informed that they still have to wait for confirmation whether there is a fibre line. How is this possible?? This is TERRIBLE service.
