Stove Changed colour first time it was used

My mother purchase the Kelvinater stove in March 2017 and she only used it once since she bought it because we have a gas stove that we use on daily bases. She went to Lewis in Soshanguve to advice them of the situation that she is facing, she was told that they will send someone to come and have a look at it. she waited and waited but no one came to fix the problem she was facing. she called them again and she was given the same story. 6months later i called the store, i spoke to an arrogant big headed lady by the mane of Thandi, there is nothing that she helped me with as she was answering all things i never asked her, she,s so arrogant i dont even know why she is in sale if she doesn't have the patience to deal with clients. I am so disappointed in the over service of the store, the stove if still under warranty, they should have claim it under the manufacture warranty and that was not going to coast then anything. Now i called they they are telling me that i must call them after 30 day from today, no that they will call me back i must call them, now tell me were in after sales service there.

i am so disappointed in Lewis on how the handled this whole situation we are facing as their clients.

will buy form Lewis and never advise any one to go and purchase any good fro the.

If this issue is no resolved by month end i am taking to the CPA and will also involve my lawyer on this matter.
