Poor service from SMEG

I sent in a kettle that has a bubble under the white coating and it has discoloured - only 3 years old. I was told they would give a R2500 trade in and that I could buy a new one for R3000 once the trade in was deducted. I will NOT do this as it is a manufacturing defect and find it very offensive. Extremely adamant and unhelpful. Lost a loyal customer!!!
