Repairing of the car KIA Seltos

I took my car to Brooklyn Motorlab for repairs. They first ordered a wrong part and later managed to get the correct one. The accessor from Momentum came to see my car for a separate case. He said to me the panelbeating was not properly, and the part that was supposed to be fixed is not properly aligned. I was promised that it would be fixed. It is not fixed up until today. Let alone the service I received from one of the staff members who said to me my car is empty, meaning it doesn't have petrol, it was deliberate for me not to fill up petrol cos my car didn't have a technical issue but needed to be fixed and be parked in their premises. I don't know what is the petrol for.
