I was ****med

Am writing this with heavy heart. The business called Vuyelwa holding(Iphone_Gadges67) ****med me R10000 from August 2023. I actually paid them R12000 for iPhone11promax, but they failed to deliver, they only gave me R2000 around September, our agreement was to pay installment of R2000 every month, but they failed to do that and blocked me. So please help me to get money back.
