Empty promises

I purchased a Jurgens trailer 7 days ago, I was trying to negotiate the price a bit but ended up paying what they had it advertised for, the day of collection I asked the sales man if the Admin fee I am paying is for covering the registration and licensing fees, he said no that's included in the price and me being a first time cash buyer I asked him for the Natis documents as I left (Not knowing they need it to do change of owner ship and registration) the salesman informed me that I would get it within 21 days with my license, so up to this point I was happy and went home, yesterday morning I got a Sms saying my papers were ready to collect, I was shocked as i was informed it would take up to 21 days and it only took 6, so here is where things started to go of track.

Right, so I quickly Googled trading hours, it says 18:00 I arrange to get off work earlier, drive all the way to Randburg from Montana, I get there at 16:45 to see a sign on the door the collections office closes at 16:30, there was nothing like that said to me or anywhere on the website, I complain at the manager, the manager sends someone else to look in the office, we find nothing the manager than tell me he will send someone today to drop the papers off, that also didn't happen I ended up sending my wife she gets there and only gets handed the Natis document, no registration or number plates and I get informed I must take the trailer for the test and register it myself, I would understand if it was a 5 or 6k trailer, but this is a R60000 trailer, I was told the registration will be done within 21 days and my wife was my witness

The trailer was missing a couple of reflectors and some reflective tape, so I am 100% sure if I had to take it like that it would have failed the test anyway
