Unhappy Customer-Nighmare purchase

I purchased a Hybrid gas Heater from Takealot in April-2022. I had not opened the item as I live on my own and do not know how to assemble it. In June-2022 I had family visit me from Jhb, I asked them to please assemble the item for me. Upon opening the box we found that the one bar on the electric side was cracked. We then attempted to connect the gas side as it was very cold. The gas side ignited after a lot of attempts, however the panels never lit up and therefore never produced any heat. The next day I took the appliance back to Takealot as the product is damaged and does not work. After a few days a consultant emails that the product is user damaged and takelot will do nothing to assist. I emailed back explaining the situation and highlighted that I NEVER GOT A CHANCE TO USE THE PRODUCT!.(Pictures were taken to show that the heater was never used) The next consultant emailed and totally ignored me and said the product is being shipped back to me. I am aware of the 7 day return guarantee, however under the circumstances I had 7 days was not sufficient to check that the product was working. Continuing a few days after that, I had several consultants emailing and asking the same question but never addressing my issue. I then called the customer care, I got promised by Fekela and Verna that they would speak to the assessment department and management and call me back the next day with a solution. To date no one has returned my calls. I asked Verna about the 6 month guarantee and she was unable to advise what that guarantee was for. Takealot talks about guaranteeing a smile on their customers face, however they have made me cry, cry to get anyone to understand or listen, cry that they expect I should just flush R2000 down the drain and sit with a product that does not work. I have still not received the product anyway. I strongly recommend that appliances as such should never be bought from such a store. They do not care about their customers and they do not honor their smile guarantee or any guarantee for that matter.
