No after sales service

Purchased 2 of thier 6kva diesel generators which works very well but i noticed one is leaking allot of diesel all over the floor after 2 weeks of my purchase (generator only has 12hours on it). You try and get hold of them but the phone just rings, i sent them an email to which their reply is i must bring it in, after explaining that the generator weighs 155kgs its not that simple to just bring it in I just get ignored. I wouldn't recommend them their after sales service is non existant once they have your money
