Anyone had their Wimax balance zapped when new portal was launched?

Hi all,
Just got back to Tripoli after a few weeks away and noticed that when I plugged in my Wimax router (after being off for 3 weeks), it no longer synchronises (flashing LED).

Went to check the balance at the wimax customer portal here LTT Ecare - and noticed that my balance for the Wimax is Zero (or at least it looks that way). They've also complete redesigned the website - looks much better, but the side effect of this change is p!ssing me off!

Account Type               Unit  Amount  Valid Date 
WiMax-volume account         -     0 B    18-09-2010 00:00:00 
Prepaid master monetary account  DIRHAMS  320000  01-01-2037 00:00:00 

The monthly reset date was 18th so I should have 10G available.

Just wondered if anyone else was facing similar problems or knows of an English speaking number I can call instead of dragging myself down to Sigma at Green Square (where I bought the service). Unless of course someone has managed to put my user/password into their router - but they'd have to be an employee of LTT or Sigma to know the details.

Thanks in advance for any advice.
