Their support has refunded me fast when I requested.
I bought a number but didn't know that I had to provide residency for said country(Portugal), so I contacted their support and they refunded me within few hours, honestly even though it didn't work out at least they guarantee that they'll resolve your problem. Leaving a 5 star review even thought it didn't work out for me but as this process normally would be a hassle in other SaaS providers it was resolved instantly
