I overhauled the car. Although on the car's maintenance booklet was registered the change of the habitat filter (2 weeks ago), with the service stamp and the date of performance, I saw that the invoice showed 200 lei for filter + installation. -I forgot through that stack of papers, to see exactly what I pay. After long discussions and observations, they deducted this totally incorrect payment, for an unnecessary operation, only for some extra money. Looking further at the operations performed, I saw that there were, however, other unjustified costs, but my opinion still did not matter.
