Worst service experience ever

Worst service experience ever. I bought a stove from Game at east rand mall with 2 years extended warrantee and paid for installation from their own people as they said that would be the best preference as i wont lose warrantee if they do installation i ask if it was all i needed the sales person Lucky and Sales assistant Xoli Mlambo said it was all i needed so and paid for stove the delivery installation and extended warrantee on 31/10/2021. Once they delivered the stove a few days later and installation team told me i needed a skeleton for the stove that was not included i went and bought that as well and the stove was fitted into the skeleton but till today the stove has not been switched on as the installer said he cant test it he doesn't know how there is no cables connected for power what so ever. After that i asked to also put up the extractor fan again their was a issue and the guys told me i needed to buy the whole kitchen unit with cupboards they cant help me without it.They also made me pay another R600 CASH to fit the hob on top of the stove in the skeletal which they also cant confirm if the unit works as they gentleman explained he doesn't know how to test it.After this i phoned Game they were going to call me back which till now has not happened on Saturday i went to the Mall again to try and resolve in person and was told that they cant refund me as they unit has been delivered and they cant do anything for me , after explaining that i will report them the lady told me i can go they are not worried.
