disagree with you and only refund to wallet you provided and not the one you paid from... If I were DZ I would only refund to wallet paid from... If you can't recieve from the wallet you paid from then there is some other issue and is likely your's not DZ's.
I can absolutely receive from the wallet I paid from. Problem is no payment has been issued. If they did issue to the address paid from, why can they not tell me that or reply in some manner to requests for information?
So your saying they should not send payment to an address that I proved was mine, by signing message, along with my initial payment? The same address that was on record to be given distribution payments to... You must be confused.
