New Upper A Arm Troubles

I never said I wasn’t willing to return the part, the issue is they don’t care about making it right for the customer. If I want a replacement I am to wait for them to have another production run in a few months, forget the fact they made it wrong. And any time I tried to explain to them it was a bad part I was told “you don’t know what you are talking about, you just care about how it looks.” The other arm in the package was fine, no issue, bar passes thru perfectly, the tubes welded on square.
