Car has been at panel beaters one month & counting

A month ago, I booked my car into Targa Panel Beaters, Centurion, upon Discovery Insure's instructions. The car had some damage on the front-right panel, the front right headlight and a small dent on the bonnet. I would classify it as medium damage, not too much, not too little. The car was perfectly drivable. Today it has been one month, and I still haven't received my car back. With every other insurance company I've ever been with (Budget Insure, King Price), I've never had to wait longer than a week or two at most. The receptionist at Targa said Discovery is the only insurance company who regularly sends out an inspector to keep an eye on the progress of the repairs, as well as making daily phone calls to find out how it's going. But even so, it's been a month, and I've heard nothing from Discovery. I phoned Discovery on Thursday morning (25 June 2015) and they essentially said there's nothing they can do. Immediately after that, I sent an email of complaint to Discovery (at 08:23am that day), and have not heard anything back from them yet. How can it take over a month to fix damage that wasn't even so great? And why am I not hearing anything back from Discovery? ***
