Dissatisfaction on receiving cheap and wrong product under false pretence

I ordered a pair of shoes that was meat to be prosthetic to aid my peripheral neuropathy as the website for Modern in Capetown look pretty professional. I received the shoes via Buffalo Logistics only to find that the shoes came fron China I presume TEMU. I emediatly e mailed Modern in Capetown to tell them of my dissatisfaction of the product. After about 6 emails of telling them that I wanted a refund of R945.00 and numerous threats the agreed to pay Back R145.00 I futher threatened them and they finally gave me a futher 15% of the total price. So I lost the rest and gave the shoes to a needy person as they are just normal walking shoes. I would advise everyone to be careful what they order from Modern Capetown.
