Registration Issues- Contacting the CFA- Is it possible?

Hi all- I made a last minute decision to sit for L3. Trying to register before the deadline, but my account appears to be locked and I’m unable to reset it with my CFA ID & personal information, so trying to call the CFA… Have also emailed them. Haven’t heard back from the email yet and keep getting hung up on by their calling waiting service. Anyone have any luck getting in touch with them over the phone?
