Not enough product information on website/refusal to return my money for a POS stove I no longer want

I purchased a Defy 4 Burner Gas Hob and Stove Black DGS168 (gas stove) from them on 23 January 2023 and requested the stove be delivered to my new place on 2 February 2023 which they did. When the delivery people came through, I asked them if they were going to set it up and they said no and that I must just connect the gas cylinder to the pipe to plug and play. My partner then advised me that I would need to get a professional gas installer and certificate of installation in order to set up the stove otherwise my warranty would be voided. Nowhere on the website or product description did Game stores mention this. I reached out to them to find out if they had gas installers and was advised that they do not offer gas installation services even though they sell gas products. I found a professional gas installer named Hilton Mashonganyika on the Kandua website who came to set up the stove. He then advised that the stove was not sparking and therefore not switching on so he could not issue the certificate of installation since he did not complete the installation. He gave me a damage report which I sent to Game and I advised Game and Defy of this and they sent a technician to view the stove. Initially the technician said he would come on Friday 11 February 2023 but nobody came and when I called they advised that they were in the area and tried calling me but nobody rep****. There were no missed calls on my phone nor did I receive an SMS notification from Telkom indicating that I had a missed call for that day. They advised that they would come on Monday 13 February 2023 but did not advise on a time. They arrived around 3pm and advised that the stove is a fully gas stove so I would need to manually switch on the stove with a lighter if I wanted to use it. I was not aware of this nor do I want a stove whereby I have to light the fire as though we in a village somewhere or on Survivor so I advised that I want to return the stove so that I can get a electric & gas stove that does not require me to act like a caveman everytime I want to cook. Game advised me that I need to send the certificate of installation. I advised Hilton of this and he issued the Certificate of Installation which I forwarded to Game on the 13th of February. I had initiated a return request on the 8th of February. It is now the 16th of February and I am still stuck with this godforsaken stove that I have never used but they are busy making me jump through hoops just to return. I have been without a stove for the past 15 days and the Game website states that returns should be done within 30 days yet they are dragging their feet to collect their stove and won't let me go drop off the stove either. After this review I will also be submitting a report to the Ombudsman because this is nonsense.
