Makro / Trojan - terrible service & products

I purchase a Trojan 120 spinning bike via the online portal, on the 14th of September 2021 it was delivered to me. I assembled the product on the 17th of September when I realised that there was an issue with the bike seat. I immediately logged a query with Trojan customer support and a lady by the name of buhle assisted me. I explained my problem and after all the required invoices/photos etc was sent she said that a technician would have to deal with this. I agreed, however I did confirm that i was not comfortable with somebody coming home and if they could please assist me remotely. I received 4 calls from their techs all during working hours and everytime they called me i explained that they will need to call me at 4:30pm when i would be home. This was 3 weeks ago. Frustrated that I could not use this equipment that is brand new collecting dust , I logged an online return with Makro, a lady by the name of Zama gave me call I explained my grievances and she requested for all the communication between Trojan and myself, and that was the last I heard from her. I complained to Makro on Facebook messenger a multitude of times and all i got was the sample response ''We have escalated the matter'' I received a call from Makro Toti a few days ago, a gentleman tried to assist me, but i had to explain the entire scenario again as Zama has deserted me, despite me trying to email her. I explicitly explained that I do not want this bike, I do not want to deal with Trojan, as their customer service is a nightmare, and it has already been a month and I cannot use the item that i paid R3000 for. I am irritated and very upset, all I want is for this bike to be returned and my money refunded so that i purchase another bike that is not Trojan, Makro keeps giving me the run around and it is ridiculous the lengths that we must endure to return a less than satisfactory product. I tried calling Makro Toti today for feedback, i spoke to Rani from sporting goods who says that a tech must come and assess the product. I do not see how this is my problem, you need to come take this bike and you can do all the assessments you want, I just want my money back.
