Campmaster Wilderness 100 - Poor construction and service

I purchased a CampMaster Wilderness 100 trailer from Makro in November 2023. We took the trailer on holiday to Namibia.

The trailer quickly started giving problems - first the jockey wheel kept coming lose and dragging on the floor, to the point that we had to tie it up with rope every time we drove. Next the back hinge on the trailer roof started to tear loose (note that the gravel roads at this point were in excellent condition). Things culminated when the hinge completely tore loose causing the roof to pop up and the tailgate to fall off. After the tailgate had fallen off, the trailer lost all structural integrity and joints started coming loose in multiple places.

To put the cherry on top the spare wheel also tore off the undercarriage, and when we tried to secure it to the roof-rack, the roof-rack itself bent.

We have been trying unsuccessfully to get Makro to honor the trailer warranty and/or their returns policy for over a month now. The manufacturer initially refused to honor the Warranty. The reasons given for refusing the warranty were that (a) we overloaded the trailer and (b) we drove on gravel roads. I sent them photos showing that there was nothing on the roof-rack before we had to put the spare wheel on it. I also question how they can sell a "wilderness" trailer if driving on a gravel road is considered a breach of warranty?

After challenging them on the Warranty I have received no further update from either Marko or Karet.
