RTP is set up to ONLY sell to legitimate dealers. Are you a dealer? If so, you are filing business taxes and claiming the profit from the difference of buying wholesale and selling at retail or higher prices. You can claim that wrong part on your business income taxes. It is not direct money but you can show it as a loss and reduce your tax burden by that amount which is essentially money in your pocket.
If you are NOT a dealer but are pretending to be to buy wholesale, you should be the last one whinning about getting the wrong part. Look what you are doing? If we get screwed when we are doing something wrong, we should never complain.
I am hoping you come back and confirm that you are a bonafide dealer by providing you dealer name and business license.
If not, you have potentially bigger problems coming than getting a wrong part and having to keep it.
