Poor Workmanship by Nedbank Service Providers

We had claimed for water damage to a cupboard through Nedbank Insurance, to which they sent their service provider, LT Contractors. <br> <br> Firstly, it took months for the contractor to actually show up to do the job after assessing it. I had to take off from work on several occassions as they said they were coming but did not show up. When they actually did show up , they brought the wrong size shelves and did not bring the boards to replace the ones that were actually damaged. It then took them another month to come back and bring the right boards, which was poorly cut, not fitted correctly (lose backboard, nail thumb-tacks and not brackets, *****ed holes and damaged board with hinges, etc). They also claimed R13500 from Nedbank Insurance, and when I requested an accessor (3 times with 3 different consultants) to see the poor workmanship and damages, and enquire as to how a backboard and 4 shelves could cost R13500, they tried sending the contractor back instead, stating that it costs R4000 to send an assessor.<br> <br> How is it logical to pay R13500 to a contractor for shody work and chipboard shelves but not R4000 to an assessor to validate the value of contractor's claim for work done?
