Bad installation of TowBar

On the 10th August 2023 I purchased Duster 1.5 dCi EDC 4X2 Intens MY21, which in included the fitting of a Towbar by your Service Department. To my dismay, when collecting a Skipper Trailer/Camper from Port Shepstone today, I discovered that those who fitted the TowBar did not put in the Fuse so that it would function correctly. The Fuse was missing. After much frustration and getting help from Renault Port Shepstone, this was resolved. This kind of situation should never have happened. Really unacceptable workmanship.
