Bad and disappointing after sales service

I bought a Kitchenaid 16cup processor at the end of November,2014 after I saw the you tube video. It seemed like an amazing unit. It has not done anything that was shown on the video. When you put any food inside, the motor stops turning. The dicing unit just clogs up and does not turn. I went back on Saturday to the store to return it and was told that It had to be sent to the supplier and I must wait 6 to 10 days for assessment. I am disgusted with that kind of service as the unit is still brand new . After spending R6500 on the unit. I feel that it should have been replaced. This is very poor after sales service. I don't know if I can trust any future purchases from Hirsch's. I expect action immediately today. I went into Wings group and told them the same. I demanded them to try the machine whilst I was there and it did the same. Now I am waiting for an answer. Total disappointment in Kitchenaid. My cheap kenwood, I used in a restaurant and never once did it fail me. This unit I bought for the house and it sucks.
