Seller- ACE Photo sent wrong item. After several lengthy telecons with ACE, I returned it under an RMA (I had to pay return shipping), with instructions to send correct item. Instead Ace credited my charge account (an incorrect amount). After several additional telecons, Ace credited my charge card with the balance due me (not including any shipping charges). Then to get the correct item, ACE processed a new order (including another shipping charge) and it presumably is in the mail now. Original order was placed May 3; it's now June 2.
