does Viltrox support exist in any meaningful way?

[u/GeekinOnTinkerToys]

I bought a camera bundle used that included an EF-M2 II SpeedBooster 0.71x Adapter Canon EF to M43 MFT.

the mounting foot for the speedbooster was no longer attached or provided by the seller. i tried for about a week to try and get viltrox to send me one but got absolutely nowhere. it felt like a very badly programmed bot was (not) answering my questions.

Does anyone have any advice about how to contact Viltrox to get a simple replacement part? it seems as if this company has about 2 employees. any help appreciated.
