Is Byethost (Domains SecureSignup) having problems with their billing system..?

Is there anyone else in my situation..? I am trying to re-new my domain with Byethost and it seems that they are not able to accept payments (their "Add Funds" page is blank; I have tried with 3 different browsers, and 2 different computers).

During the last 48 hours I've opened a couple of tickets but all I am getting is "canned" replies.

This is unusual for them, as they have a good reputation of getting back to costumers in fairly quick time. Also their Live Chat showed "Online", but no one was available to talk... Calling their UK number got me to a "Leave a message" recording.

The reason I am asking here is because my domain will expire on January 5th, they are not providing any payment options for domain renewal and they are not replying to their support ticketing system...? Is there anyone else experiencing this..?

PS - What will happen if my domain expires and they are too late to reply or worst, not replying at all..? Will I lose my domain...? I've tried transferring the domain but because it only has less than 72 hours to expire, no other registrar will accept the transfer...
