Not happy with 120000km service received from Hyundai Springs

Took my grand i10 for a 120000km service and the consultant called to inform me that the technician noticed a fuel pump leak and requested R2800 to get it fixed and I said no they can continue with the service and I’ll fix this later. When I collected my car driving home the car smelled of fuel so bad but it was just 10 mins drive. Next day I had to drive longer and I couldn’t because of the smell. This was not the case before this service so whatever happened, happened when they were working on my car but this unfortunately is now my problem.
