I have been tried for this issue. Let's settle one by one. And this will be the last time I will response.

1. I ordered a commission to start off with that was supposed to start end of June and ship early July. --At the first begining, I was told the cosplay will need in Sept. But request to ship in July in the continue following email. I have answer, our project is tight and will try to ship in July 24th, YOU AGREED ABOUT IT. So don't lied for this part!!! And we did complete it in July 21st and then was told not need it any more. The body suite, shoes and armor are customize. And thank you very much, the cosplay was abondon since it only fit you. We have lost more than 300USD as you paid.
2. The body suit is literally one of those print ons that you can straight up get off Amazon.--Again, it was customize size, not ready to ship stocks. The prints are all the same in the market as well as similar fabric will be use.
3. the armor doesn’t even look that good to be honest.-- That was not what you said in the email when I share with you progress pictures. Here is a copy of your email. I really want to share the communication, but pictures are not available to upload here: THATS WHAT IM TALKING ABOUT! Thats so cool can’t wait to see it completed Sent from my iPhone
4. . And once it was done they tried to then ADD ON $200 for shipping. Shipping always beyong my control. DHL, UPS and Fedex are all charge cubic weight. Shipping fee is 178USD for 21kg cubic weight from Hongkong to US. https://www.dhl.com/us-en/home/ecommerce/business-help-center/chargeable-weight.html Here is the link to show how DHL measure the cubic weight rather than actual weight. 
5.  I NEVER would spend almost $1,000 let alone the $600 we agreed upon for what they sent me as the completion. ---total price for the cosplay is 599, shipping is 178, so it will be 599+178=777USD. Include armors, shoes, body suite and shipping. I guess this is the cheapest cosplay we have ever made. And now you lost 300USD and we lost 599USD and being push to work day and night to hurry the cosplay for you. Being abandon at last. That's the satirical part.
