Dear , 

Thank you for contacting BullionStar. We apologize for the service disruption you experienced due to the 2-Factor Authentication feature not working. This most likely happened due to network issues with our service providers. 

In order to optimize the reliance of the 2-Factor Authentication and to avoid any future service disruptions, we've sent you 4 different SMS text messages using 4 different service providers that we work with. 

Please respond to us stating which SMS messages from which service providers you've received, and we'll calibrate your account accordingly. 

Please do not hesitate to contact me if you have any further questions or comments! 

Best Regards,
