Login into eBay and scroll to the bottom of the page where you can see site map. Again there will be several sections Scroll down and you should be able to find " my account" and from there click on change registration info- I have copied the link ad well-
"http://cgi4.ebay.in/ws/eBayISAPI.dll?ChangeRegistrationShow"
There you can change it. I had same issue today and I had to call customer care. I found this was still unresolved. Hope this helps you if it hasn't been solved already!
