hi ive a Jonasard ride on i got the dealer i bought it off to sharpen the blades, then when i took it out cutting i noticed the garden wasnt looking right and cutting, so i turned it up to see the blades, i noticed 1 of the blades were up the wrong way. so i got the ride back to the dealer he said the blades are bent and the cogs were worn bad, he said i had to pay 300 quid to fix it plus parts, the ride on is only 4 months old with 3 year warrenty.
should i pay it or what should i do. please help
