OP: On both phone calls I asked to speak to a supervisor. In both cases the agent promptly hung up on me. I know little about EBay but if caller just immediately demanded a supervisor and did not accept any other result, the agent hanging up on them might be the logical result. Any large organization has to have standard procedures and "I'm escalating immediately before I get my result" can't be allowed in this situation 'cause everyone would do it.
