Overcharged on customs fees

I have been ordering from Temu and allocated baffalo logistics for delivery, recently I have been allocated fast way the customs is absurd I order 10 small items no heavy duty for R640 to my suprised the customs amount to R444 almost 80% of my order value, this is too much I first paid R377 for order costing R900 I thought is becos I order items including 2x pairs of sneakers maybe the wieght is too much, but this time I cannot take, please fix this Temu
