Google offers customer support by phone.
Also, I need a number to reach support at Facebook, if you have it.
Gmail: 1-877-355-5787 YouTube: 1-855-500-2756
Never done business with Facebook, can't help you there sorry!
You can find contact information for your region/niche on their partner directory site: https://facebookmarketingpartners.com/
Judging by the number they called me from their call center is in Ireland.
You don't pay to use Facebook, so you don't get support.
Google does provide phone support to Google Business accounts, though, since those cost money.
