I wrote Velobuild highlighting this issue with the VBR177, they answered "drill it". I knew they lacked quality controls, but still...
Honestly, I have seen this "type of answer" with almost EVERY Chinese (China) sellers. It's lack of quality control , which you should have been aware of; and it's also normally that "everything is negotiable" . Also, remember QC is by sampling , not 100% !! No companies do 100% QC.
I had some issues with my trifox parts , useable but since it's new, I wasn't happy, so I reached out, got a similar response. Spoke to them professionally and they replied professionally, negotiated for a slight discount on replacement on the basis that I get to keep the old one. Used it till the replacement came, and sold it as used with minor cosmetic damage... Broke even on money side of things, and get a "friend" in Trifox.
Had some issues when I bought Sensah OSPW from Sensah , in their case, they wanted me to give a good review before they would even consider resolving the issues. I refused to be blackmail into a 5 star review before they would even "discussing" the resolution, and also they probably will not resolve it subsequently.... so gave them a 1-star.... but it does meant they ignore me. LOL..
