Morning. We recently bought a new fuel pump for filling up our ride on mower on eBay for £110. On the third time of using it it would nt work. We complained to the seller who said it had a 3 month warranty and it was a couple of days over three months that we bought it. On checking the eBay ad we could nt see a warranty but it was expired and said the as had been modified. Can any one advise if we have a case please? Thank you
