Don't sell your boat or caravan through them

In April 2015, dire financial problems forced us to sell our boat. Because we live on the East Rand, we approached Nigel Camping and Boating, who at first appearance look like a reputable, established dealership, to do so on our behalf. They furnished us with a mandate. We furnished them with all the paperwork required as well as our boat. We found out in August that our boat had been sold. They refuse to disclose when it was sold and we were not contacted by them at any stage. They are trying every trick in the book to avoid paying us out for our boat. We have been able to obtain 2 small payments so far, and Chris maintains that he does not have the money to pay us, although they have been paid in full for our boat. This appears to me to be questionable at best and ********** at worst. Be warned!
