CW‑WhatsApp Chat, Abandon Cart

I was using this service since many months, since last 20 days it was not working & my account had 25$ balance, customer complained regarding not receiving SMS, when i tested it was not working but deducting money continuously. I tried email him many times but he ignored to replied hence i come to the conclusion he runs away with our prepaid and all other client balance.
service is no longer available, as he collects advance money for Credit of Sms, he took all and runs away, i will open a shopify dispute now as well.
be aware this app is no longer in service, any payment you made is gone.
