Ford s max 1.8 56 plate intermittent starting problem

[Adam IS]

Hi hope someone can help I've Recently stating having a problem where the car refuses to start in the mornings, I have taken the car back to the garage I brought it from and he sent it to have the electrics checked and a few days later called up and asked if I had put the wrong fuel in the car as the the electrician can smell unleaded. 

I have told him this can't be as I have not put the   Wrong fuel in the car could he just be brushing me off.  

 

Thanks
