Bad service. Poor product quality

Hello. I have seldom had such poor service as I have had from Smeg South Africa. 2 of the 4 feet of our Smeg oven simply disintegrated after 7 years. The oven has never been moved in that time. Contacted Smeg parts (the address on your website). No reply after 2 days. Contacted customer service. Same thing. So for 10 days now I have had no communication from you, on any queries. We got appliance people who have just fitted the new feet because you responded to nothing. Feeble service, really. And extremely feeble oven feet.
