Cholt, first of all, welcome, then…..
my suggestion is to log in in the main page of AChat and look in the rigth side of your screen, under the “Buy A$” button, where you will find “Recent purchases”. click it and a new page appear: here you can find all the AChat stuff you had bought…..look at the them and verify about your “seat with cock”. If it's not there, iot means you don't have bought it at last….but if you seen it there, first move back to the shop page and take a look at the pose: under every one of them, you can find out if it “Yours” or if you have “Into cart”
After those simply step, if you have more problem, use the Support of the site.
Hope this can help you!
