Your not going to want to hear it but my take:

1. After they did not work you took them to a shop to have them modified so hopefully they would work. I get that you probably wanted to get them on the car ASAP but you have now modified them and expect ModBargains to take them back when they don't even know what was done to them or if they can even resell them.

2. Because of you having a shop modify them we can never confirm if the hyperflashing was the product itself or caused by you. I'm not trying to put blame on you, you just have to realize how this looks to outsiders and the company who could think you are trying to rip them off on a return if you just don't like how it looks or you could be trying to return fake parts and keep theirs etc.....

3. Not every company's website is perfectly updated. If you were worried about compatibility why not give them a call especially when the similar ones you were seeing were listed as JDM and needed to be repinned?

4. We've all spent money on stupid things but I really think you only spent money making this harder for yourself.

Unfortunately this will probably work out for you and the vendor will have to capitulate to save their reputation on the forums and it just reinforces people's behavior of "I'm going to publicly complain when I am just as much at fault". This all could have been handled by a simple return when you received the parts and realized they were not compatible with your car.

TL;DR : If you modify purchased parts don't expect the retailer to take them back
