My complain is with ebay. I have a problem and no way I can contact someone to correct it. My forwaring address is Miami 33122-1438. When I type this in the system automaticcaly change it to 33122-1008. Although the system ask my do you want to use 33122-1438 and when I say yes it change it anyhow to 33122-1008. Now resently I lost a package I think that it is due to this porblem and I urgently need the item Please advise next steps to be taken. Kind regards, Franklin Esser
