Lost login details

I have lost my login details and can't remember my security questions to my SARS eFiling account. The call center just sends me a temporary password, but that does not help me if I cannot remember my username. I'm completely stuffed on this one.

If you call SARS on 0800 00 7277 they will be able to reset your username as well and send this to you.

Thank you so much, I will attempt at calling them ASAP :)
