You paid for the purchase, but the seller did not send you the cryptocurrency.

In this case, you need to open a dispute and wait for the arbitrator to intervene.  Issues related to disputes are decided by arbitrators only within the service.

Please attach an account statement and a brief comment on the dispute - this will speed up the process.

Wait for a decision and, if necessary, provide additional information (account statement and other supporting documents).

If the arbiter has not contacted you, it means that at the moment he does not need information from you, and the proceedings are with the seller.
