Login Issue

I am having issues with my login details. I have an old account with Pnet which I have did not use for many years and the email for that account is no more in use. I then created a new account but it says my ID is already in use, ( Sometime during the COVID lockdown I sent a request with this issue a few months ago, and was not resolved. I tried calling 010 (***) which is the advertised number, but it goes to Career Junction. I cannot say I won't want to use Pnet anymore cos the advertised required jobs for myself is on their site only. Kindly please assist urgently.
