Worst customer support. There is no phone number or live support available which makes it unreliable for business purposes. I have submitted a request on their support page and they don't give a s@!t about it. They just opened by email and they didn't have any time to respond to them. My email client shows that emails are opened. You should dedicate a full department for customer support. They took my money and restricted my account immediately after upgrading. I regret choosing Telnyx over you guys. Will shift to Telnyx if issue doesn't get's resolved.
