Samsung washing machine

We have a 4 year old washing machine that the motor has burned out. There is a 10 year warranty on the motor. Samsung have made us wait over 2 weeks for an assessor to come out, then claim that they are going to replace the mother board, which is not faulty or under warranty. The damage report does not state that there is a faulty mother board whatsoever. We have spent hours on the phone trying to talk sense into the person on the other side of the phone. Really disappointed with their terrible customer service and care.
