I am a new member in Paxful I deposit bitcoin and try to set trade

And the first trade I set wrong. (Set the wrong limit)

There are buyers open to trade with me (1.8btc). And press PAID. But in fact, there are no transactions at all.

I try to let the buyer cancel the trade. But the buyer is trying to open the link he sent to see before canceling the trade. I did not dare open it.

I have been waiting until the time of the dispute and open the dispute for help from the staff until now. 10 hours passed, not yet resolved.

Do I want to ask the user Waiting time for judgment How much time?
What should I do I'm afraid to lose money.

Thank You
