Does anyone have a WhatsApp contact to Waltly?
Nope. Although Whatsapp is a secure app. I don't trust using Whatsapp for doing business with foreign companies and people I don't know.
When I dealt with Waltly, I E-mailed back and forth with Sumi to communicate. This worked out well for me.
Edit: I was invited by Waltly to let them communicate via Whatsapp, (along with other companies in the past), I deleted the invitation.
