You pay upfront - you don't (to my knowledge, I could be wrong) hold payment until receiving goods.
@Qingdao Sigma Chemicals my order history shows it is through Joy Liu, but there is no profile pic as you stated. However, this could have been something you removed, so I cannot confirm nor deny this dispute.
I want an answer from
@mokola about why you aren't posting evidence of the following:
a) showing that they admitted the stoppers were fucked
b) showing that you did indeed order from
@Qingdao Sigma Chemicals - as I could do literally right now without posting an Order ID
c) showing the date you ordered without posting the Order ID, as I could literally do right now with my own orders.
Without these claims being backed with evidence, it's hard to trust words alone. You also did begin this entire ordeal with the lower purity as a point of contention, but then later backpedaled and said that it was fine. This was after another separate message outside of your OP stating that the quality was "less than what would be acceptable, even given the lower price" (not a verbatim quote). I understand now that you don't care about the quality, but the point that you made in multiple messages as part of your grievance is not going to be well received without evidence. You refuse to post testing results under the veil of "protecting your group", which is bullshit. Either post the results or never bring the results up fucking at all.
One of you motherfuckers is lying and I'm going to find out who!!!
