Contact
Two channels. Both answered by a person.
There is no ticket queue and no bot. Send the platform, the country and the limits you need, and you will get a firm quote, a realistic timeline, and an honest read on whether the build is worth doing.

Response time
Median first reply under fifteen minutes during working hours, and rarely more than a few hours overnight.
What to send
Platform, country of residence required, limit or feature you need unlocked, and your deadline. Four lines is enough.
After the sale
The same channel handles follow-up compliance questions weeks later. You are not passed to anyone else.
