You have selectively used information and ignored facts that do not fit your narrative. For example, jper3009 did receive responses, both from TheQuin and their email support.
Once again, are you sure about that?
Yes, I'm sure.
TheQuin replied to the user on January 15:
I'm sorry if I missed it. Please send me a PM with the details.
And jper3009 himself confirmed that he received a response:
I'm not sure what happened but this is the explanation I got from TheQuin
"As a general observation when 2 outputs on the same transaction are sent to the same deposit address the first is processed immediately and then the server has to go back and reread the transaction before it processes the second one. That causes a delay in the second one showing up which often causes people to incorrectly think they only got one."
However in my case I was not credited the second transaction until date. I made 2 deposits, one was added and the other wasn't.
Yes, I'm aware the user still claims that one of his deposits wasn't credited. However, for objectivity, I prefer not to draw conclusions based on a single complaint without attached evidence. It could be a legitimate issue or a simple misunderstanding.
