Logistics confirmed that we didn´t received these 20pcs.
The issue is that we cannot detect by system because maybe they were entered with wrong 8digits (92446831 and 92446832).
Because of we saw them here in the office (a member of sales team took them as samples) we asked to Logistics to double check comparing system with physical inventory.
We are waiting for their response.
Please let us check this issue and we´ll come back to you
