There are several concerns of yours that need to be addressed.
The first is the question of testing own our raws. My issue with this type of criticism is that initially we were asked by the community to test our own raws/product before selling. We have had individuals voice they that do not want to be "guinea pigs" for untested product. We follow up with this testing and now we are being criticized saying that these self test are not of any value, where in the beginning it was the community asking us to do this self testing in the first place.
Every few months we have accusations of alternative handles or accounts. I have been transparent from the beginning and have continued to do so for over a year now. This is the only and official account used to post and comment on 24k. There is no way we can prove we don't have alts, because as another user accurately stated "you can't prove a negative and the burden of proof is on the person making the claim". I can only say that we do not need to operate in such "shady" ways when we have always been a proponent of honest dealings.
I have answered your refund/replacement question in an earlier post of yours.
In regards to the testing being worthless, I believe the below user sums up our sentiments nicely
Please let me know if this has addressed your concerns, thanks.
