problems signing in on Ebay?

Lately when I try to sign in on Ebay, they will not accept my password. I type in my secret question whenever I "forget" my password. They say they'll email me about it but never do. I emailed tech support and they just give me the run around. I also tried to re-register. First with my normal info but they wouldn't accept my password. Then I try again with a new password but they say that my ID is already taken. You would think that with my name and address being the same that I'm the same person and not a strange coincidence. Ebay is of no help but I'm hoping someone here has the answer because. I may need to re-register with a new ID but I shouldn't have to.
