Usual email I use is:
[email protected]
The "Contact us" form may be faster as it may redirect to the right department depending on what your question is:
https://faphouse.com/support/contact
I don't have a direct contact.
How long have you been awaiting their responses?
Oddly... I emailed them about 20 times and I think all my emails have been answered by Milanija.
If it takes longer, it may be because she has taken some time off. Their support team seems to be really small. Longest I had to wait previously was about 10 days. Usual wait time is 24-72h.
