Seller keeps on canceling orders for no reason


The seller, Super Deals GC, keeps on canceling my orders without any reason. Both times, I’ve been willing to cooperate and wait for him to deliver his code, but he would always disappear right after saying he was ready to deliver and then cancel it. Is there no penalty for canceling orders, as I’ve been getting cancels after cancels, and always have to wait for the refunds to go back to my bank? A bit tired of this.
