Rudest workers, worst customer service

Good day I am a very unhappy customer, I had purchased a defy washing machine, from blomyers in pietermaritzburg, in 2021, the machine is now giving problems. There is a 2 year guarantee, stamped on the receipt, however Defy will not swop out the machine. A repair substitutes a warranty, and there is a guarantee. When purchased the stamp of 2 years was put on the receipt. I have being assisted by rude individuals in your pietermaritzburg branch, and need immediate assistance. The consultants are very rude and shut down any suggestions, they basically told me I don't know what I am talking about. I work in sales and that is not how you talk to customers. Also if something is sold all the cpa's stating terms and conditions need to be there, which I did not sign one peice of paperwork. I have a guarantee stamp on my receipt, therefore I want a new machine.
