Could they launch an investigation once they receive the wrong item?

If they've requested the wrong Item be returned, It's done so for a reason- replacement or refund.

I've yet to personally experience an Investigation opened for the wrong Item received method.

Do you think if I bought an EVGA RTX 2060 and sent back an EVGA 1050ti or an EVGA 1060 they would fall for it? I can't really think of anything of similar weight besides the previous graphics c(spam)ards. (all single fans)

Power supplies have similar weight and size and are very cheap.
