Unable to renew. Need urgent support for GoTo Webinar.

Hi, I have already submitted support case #21967852. 

The customer support phone numbers provided are not operational since last week. Please provide an alternative way to contact support or have someone email or call me.

If the issue is not solved, we are risking cancellation of a webinar in less than 24 hours. We already paid twice and it is still not working.

Thank you,
Wallbox team
