Sasol garage

Hallo can i have some advice .

i went to Sasol to fill up diesel and i told the attended to put diesel twice ( Besides that it is written on the door) the guy put Unleaded 95 petrol in a diesel bakkie. I didn't notice or know and drove to where i was going. The car just stopped. when i checked the slip then noticed the attendant put petrol not Diesel . i then called them and they said i must come and see them.

I hired someone to tow the car back to the Sasol garage and i spoke to the manager who then agreed that i provide 3 different quotations so that they can fix my car. i have done that and now they are saying they will pay for the replacement parts but not the Labour to fix the car .

In this case what needs to be done. Kindly note that for the case of advice i will not state which Sasol garage it is as i am still consulting .
