Can I call you?

Nope. We do not have a phone number for Developer Support, and we do not have the capacity to help 1:1 on phone, sorry. We can set-up a MS teams call in urgent cases, since most cases involve information that needs to be in written form, such as ids, API requests/responses, etc. We do sometimes set up Slack channels for customers, so you can request that if you expect to be contacting us a lot.
