You have to call early morning or after lunch
No email that I am aware of. I called, was kept on hold for more than 30 minutes before anyone would answer the phone, only to be told to go to their website to download a request form and mail it in. The guy on the phone said that it was due to Covid-19 restrictions that everything had to be done by mail, but that doesn't excuse their inability (or unwillingness) to do business over the phone.
