Is this service?

I ordered a new line installation and after a month of no response I finally had enough and decided to call and ask what the hell is going on, apparently technicians were in the process of booking a date of installation for the past TWO week...not even 5 minutes passed after the call that I got a message saying that my installation appointment was booked, so I wait for the week to pass and sure enough I receive another message less than 24 hours before my installation appointment saying that my appointment has been moved...I mean seriously??how unprofessional can you get?I had to go and cancel my leave that I had put in and apply for leave again at a different date....worst part is that I phoned in because they had the incorrect address for the installation, they changed the address apparently and assured me that all is fine, my installation would now happen the following week, and also state that I have to pay a fee of R700 once-off....where the hell does this come from?I was not even informed of this!!! Now the tech guy from telkom phones me and rudely asks for my address cause he's clearly at the wrong house...this after I phoned in to correct it....SERIOUSLY?!
