What happens to you try to return things too many times to Wish?

I’m not abusing the policy, but sometimes their products suck or are defective. And if that’s the case then I let them know. Often this ends of resulting in them saying they’ll refund me the money but I can keep the item.

Now keep in kind, I wouldn’t mind returning the item - but because they mostly originate from China, Wish doesn’t want to pay the shipping again I guess.

So what happens if I try to return things too many times? I mean, surely there has to be a limit, no?
