Incompetence when handling customers

Today marks 2 full weeks since I took my car in for repairs, not only did they gaslight me when I called them last week to ask if they would have fixed the car by Friday, Head office promised to come back to me with a solution last week Thursday, the only phonecall the dealership has made to me is to tell me I need a new engine, this they did on Tuesday and have since said they would get back to me. as a 34 weeks pregnant woman whose PRIMARY car is with these people, I am beyond frustrated. Renault Mahikeng and the head office have failed me. Very inconsiderate to keep someone's car for this long. I want my car, and you will never catch me flirting with this brand ever again. I loathe incompetence with my whole heart. Put your customers at ease by communicating with them.
