Customer service

Horrible company. Can’t reach anyone. My account was blocked with money still on it but can’t reach anyone to unblock it

Thought was a solution but quite the opposite!

Customer service is almost non-existent. Too much chaos with the App, my calls only last ~2.5 min before somehow disconnects but still keeps on counting minutes. On one occasion I topped $10 only to disappear had to call for it to reappear after more than a month. Tried to reach out to them about the 2.5 min calls via WhatsApp and calling to no avail. Just being honest here …. The App is promising but as is for me right now it feels like a beta version … Slick Call needs to improve functionality of this app.
