Service delivery not up to par

Has a 4 plate gas, 2 plate electric stove from Totai. After 3/4 electric plate replacements due to rusting and flaking of the electric plates within a span of under 6 months and warping of the actual stove top; I received a replacement/ upgrade. This has not gone any better, after research I was made aware of the fact that I would need to put in their main switch for my warranty to be valid, stove was also delivered without prior notice and previous defect was not collected at the same time. I was fortunately at home. On collection of the defect I was also not made aware of said collection and the collection company had to reach out to me on several occasions while standing in front of my house. We then determined that we had to arrange amongst ourselves to get this sorted, seeing as this had also taken quite a few months to be collected. It's been quite a few months since the new stove has been delivered and yet after numerous emails I have received no feedback with regards to connections of the new stove or when this will be done. Never expected such bad service delivery as the staff were very helpful in the beginning of the process of assisting me in getting their product sorted. Now I am unsure of the product as well as the service based on the warranty it still is under, as well as the future service delivery at this point
