"Mixing our order up with someone elses"

We have been building a new home. We had all the cupboards cut, with all the dimensions, 100% correct, given to Buco Nelspruit, to be cut to spec, to find out that they mixed our order up with someone else's. Buco have been made aware of this too. The inconvenience of 30km of travel up and down to get this mess fixed, over again, with no compensation, is at best annoying. This comes with obvious lack of supervision when the project is handed down to the "carpenter" "cutter" whatever you want to call the person/s who are supposed to cut the wood pieces, to exactly what the client ordered! Guys, all I can say is, get your ducks in a row and do it right the first time please, and supervise your staff.
