3 months & counting for voice line

I ordered a voice line 3 months ago (early March 2015). I was promised an installed line within 21 days. Twenty one working days. Since then Telkom have sent 2 technicians to my flat, none of whom are able to install a line from the building DB to my flat ****erally right below me, 2 floors down). Others on my floor have Telkom lines but one excuse was there is no infrastructure, which makes no sense. Now apparently my job has been paused because they're upgrading the exchange. What about the 21 day promise?? How long must I wait now? Must I try the competition?<br> <br> With all Telkom products my experience is the same: if you have a product, their service is OK. The single hardest thing to do though is to get Telkom to sell you anything. Here I am, a willing customer who wants to give them money in exchange for a service. Telkom have only themselves to blame if their customer base is dwindling, they are simply inept at selling anything.<br> <br> When will I get my line? When? Dates please, because \as soon as possible"doesn't cut it. WHEN??!!!"""
