Line installation incomplete because of fault line

On 1st of Feb I requested a normal voice line installation from Telkom. They later phoned me and scheduled the installation for the 16th of Feb.<br> After some time the technicians told me they cannot finish the install because there is a fault with the Telkom exchange line, the case has to be handed over to the cabling guys.<br> After a day or two someone from Telkom phoned me again to complete the installation as the cabling guys fixed their part.<br> The Telkom techs came out again on the 22nd of Feb, but said it's still the same problem.<br> Since then I've been phoning Telkom every day to get any update on the situation.<br> I've had a few people that tried to help me, but their hands are mostly tied. It has been escalated to the back office I've been told, but still that doesn't mean anything if I get no response and when I phone no one can really help me.<br> Today I got through to someone again that actually wanted to help me and he eventually put me through to the technical department. They, however, were just completely rude and told me they cannot help me as the fault needs to be logged and my request is an installtion.<br> So how is my installation suppose to finish with the fault on the exchange
