Haha, that was much the same as my experience:
"Thank you for registering with the Parts Online Store system.
Access to the Parts Online Store system requires that the email address used for registration be your company email address. We request this to help protect user privacy and insure that order information for your company remains confidential. It does not appear that your email address in your registration matches your company name therefore we are unable to finalize your registration."
"Please register again using an email address from your company. Or, respond to this email with information that the email address you registered with is actually your company email address at which time we will re-evaluate your registration. "
I followed their instructions and replied. After much to and fro, eventually they came clean with:
"We have checked your registration request and found that Bill To/Ship To address you have provided are of New Zealand region. Currently, Keysight Parts Online Store is available for United States customers only. However, you may contact Keysight sales partner in New Zealand for more information regarding your product. Please refer the below contact details."
Which then lead to the $100 quote for a switch....
I think some of these guys have shifted into customer service from the old HP legal department...
