Review Non satisfactory service

Had a customer who had their car in with this man, small repairs needed on the vehicle. 1 small scuff (about 5 inches) on the front (light damage).
And 2 small indentation marks on the rear bumper. The front was repaired appropriatly. The rear was not. A poor attempt at a touch up with a lack of skill to match the colour of the car. Upon arrival my customer asked could the garage to look at the wheels on the the car in regards to refurbsihing them. The garage took on the request, and in return, very poorly attempted to repair 1 wheel on the vehicle. Sanding back the paint on the alloy where damaged and then using some type of alcohold rub to remove remaining layers.
The wheel was then left completly and unfinnished.
The following work cost €150.
A breakdown of the work done:

.front bumper done correctly.
.Rear bumper not done correctly.
.1 alloy wheel left sanded back with surrounding paint and coating stripped off.

This is not a fair price for the poor work that was carried out on the vehicle.
