Horrible customer service and repairs

After waiting a month (I was told 21 days) for my 2 plate oven to be repaired it came back with a rust inside and in the specifications I asked that the rust be removed as well as it is still under warranty. The stove plates were not even done properly .I have emailed to raise the matter but no response until today. It's been 7 days waiting for feedback. This is horrible service.
