Recover my PIN code.

Hello,

I have sent contact form, My case - [CASE: 727808].

I lost my PIN code, so now can’t open my phone. I have not yet registered for ‘’WebBilling’’ so I can not go to my account and recover it through there. In order to register I need my account number which I have, but password is being sent to my phone which I can’t open, I have not  received anything via e-mail. Let me know what I need to do to get my PIN code?

Thank you,
