How to Contact Nextdns Team: Affiliate payout failed

How to contact the Nextdns team? I requested an affiliate payout of around $53, but my PayPal account is registered in Nepal and cannot receive incoming payments. 

The payout amount has already been deducted from my affiliate balance, but I have not received the funds in PayPal.

I have emailed multiple times via Gmail and also messaged the staff here, but haven't been able to receive a response.
