Problems with unbinding-not receiving verification mail

I’ve been trying to unbind one of the devices in order to log in in another one. I’ve requested numerous verification codes but it seems to not reach my mail-or reach it after 10 minutes which is not accepted by the pop up window because it has a 5 minute limit.
I have been trying to log in for hours now, still nothing. Verification e-mails reach my inbox after 10-15 mins and then it is too late for the verification code as it is timed out.

Hi @despoinasidiropoulos, We apologize for the inconvenience. Kindly provide the email address associated with the D5 account you wish to unbind. You may send this information privately, and I will promptly check the issue. Thank you.
