Smeg Products Faulty and Sub Standard

The plastic knobs on our Smeg gas hob all disintegrated after 4 months of use. Smeg Jhb tell us it is due either to them falling on the floor when cleaned, or us using oversized pots. Pathetic, and arrogant from them. They want to charge us R180 less 20% per knob! And the Smeg extractor fan we bought arrived without a motherboard. They replaced it with another extractor, but the technician found that it was also faulty and did not advance to fan level 4. He was amazed that the knobs on the hob had cracked and fallen apart and he promised to sort this out with head office. Rudolph Pieterse at Smeg Jhb insults us further by reiterating that we have to pay for the knobs. The hob is now displayed in our brand new kitchen for all guests to see, with one functioning knob to operate the burners. Not a great advert for Smeg. We will never buy another Smeg appliance - the look fine but are manufactured with substandard parts and their after sales service is arrogant and disappointing. I will shortly be taking a sledgehammer to the hob and will post it on You Tube for their enjoyment.
