Supplying defective goods and refusing returns

I've made 3 orders with Diy electronics over the years, every single time I have received deflective hardware and customer support has either refused to replace or return or they delay until it's, no longer worth the time and effort.

Most recently I bought a Ender 3 v2 3d printer that arrived damaged and missing parts. After a week of being in communication with their support team, who were rude, could not offer a solution and would not replace the machine, I landed up having to source the missing parts elsewhere and repair it.

Not being able to phone support, waiting days to respond on email and playing dumb or delaying is clearly a strategy from Diy Electronics.
