Issue contacting support for enrolment

Hi, i can't get through to support. The call back won't accept my mobile phone as it's registered to a personal account. I've tried my internet phone number, but the call back keeps failing, presumably because there's an extra step with my RingCentral internet number where i have to press 1 to accept the call. I've tried to use the email form, but this does not send my message, i get a small blue circle spinning. I've tried to use Safari and Chrome with the same result. I can't find a number to call anywhere or a direct email. I understand that i could register a different number, bu tthis is not a long-term solution. Are there any other options so i can complete my enrolment?!
