Defective Exercise Cycle

I bought a exercise cycle from on line Makro and i collected it from Makro Centurion where they assembled it for me. When i bought it in September 2018 I was hardly using it as was travelling extensively as i was doing a project in all the provinces. i stay alone at home. the project commenced in August and was going to be completed in Feb 2019. In November i was involved in a car accident and i was hospitalised. Later on i noticed that the the rubbers are cracking which I found worrisome as the bike was still new for that. the electrical cable to connect it to the socket is still in the box to prove the bike is hardly used. I then called on line service. They later called me back and advised me that i must take it back to Makro where they will exchange it and give me a new one. I took it back and when I arrived there the online dept took me to sports sec tion where the manager at first said they will remove the cracked rubbers and replace them with a hard alternative and which i objected to as this is not what what i purchased on line and he later said he will remove the handles from the handles in the other cycles and instal them to my cycle. I also objected to this as this is not what we agreed on and i asked them what if the product is defective? I cannot take that risk. There was an argument and I left the shop and the bike in the shop to this day. That I will not accept a defective product. It is about 2 months since it has been with Makro Centurion to date. The Manager did not care about the needs of the customer. whether or not there is a possibility that there be problems with their product. I will appreciate your help for this not to happen to other customers. my number is ********** 129. Shoeshoe Mopeli
