Uh-oh! Hope there is no robot in our network… Let's get you back to hear human voice: Check your mobile phone signal level.
Ensure you at least have 2-3 bars for excellent voice quality.
Wait for 10 minutes and try to make call again, perhaps there is a spike of users during that time using the network.
If the issue still persist, get in touch with our Live Chat in Self-Care or use the Online Web Form, and we get back to you with the solution.
