Help Needed: Unable to Reset Password After ID Deactivation

I am unallocated & resigned. On 28th may HR called me asked are u ok if we relieve on 30th May. I said it's a bit difficult for me to settle things as it's relocation & need to check with the joining company also, Then asked an extra 2 weeks which they told me to send requesting an email. I sent & Took some sick leave. Another 4 days for LWD so pinged HR told me I didn't get anything from separation, all ok on LWD 13th then HR told to postpone to 20th another week. Again I changed my joining & booking in the next company. But My emp ID was deactivated on the 16th, I sent an email from the personal ID active but the password is not working even in Ultimat***, I am not able to reset the password to do anything. Sent email to helpdesk. Can anyone please help if anyone faces the same situation.
