contacting opencascade

Hi, I would like to get in touch with the commercial side of opencascade. This is tougher than it seems since they don't seem to pick up the phone and they don't respond to emails.

Does anyone know how I can get in touch with them?
their telephone number
+33 478 651 030

Has not given me much joy.

Hello Roland,

We received both your requests to our Contact Form where you provided your two email addresses - and - and I already replied to both. If you did not receive my replies it means there is a problem with your mail server.

Yours sincerely,
Sergey Zerchaninov

Sergey, I'd like to know where I can report for a possible bug in one of the comercial OCC-samples?
