Hello, After registering I get following error when trying to use my login details: "Your account registration was rejected due to problems with the data provided or other irregularities. If you believe this rejection is in error, please see our FAQs and Contact Channels page or work with your eBay representative directly."

How do I sort this? I've already sent two tickets using https://developer.ebay.com/contact-us form and didn't hear anything back.
