Disgusting service

On the 8th March 2022 I bought a Trojan exercise bicycle at makro Springfield. The bicycle kept sliding and didn't work properly on levels. I too the unit back to mackro on 19th May 2022 and told the customer service I have to let the bicycle go in for acessment before requesting for refund.i was contacted on 1 June via sms to collect my bicycle. I was told by Melanie at customer service the chain and belt was reset and I must take the bicycle back. I asked her if she is aware of the CPA and my right to have repair or replacement or refund within the first 6 months of purchase. The reseting of chain and belt can only be done once dismantled. This issue must be raised between makro and their supplier. I left the bicycle at makro and want a full refund . Please teacher Melanie from customer service the rules of cpa. Repair ticket is ***
