Hi am new to this community and have some questions about Payments

I property is in Africa and as such the account attached to the property is in Africa as well. I have a guest staying who's leaving tomorrow and I am yet to receive payment or hear anything from booking in regards to this. I have been trying to reach booking for two days now without any success. Is there any one who knows how these things work or can shed some light as to how to get InTouch with booking or Pulse through email by phone?

Thanks in advance.
