PLEASE HELP!!!

I have numerous requests by other TAX PRACTITIONERS
to transfer tax types (e-filing profiles) to them -
which I would gladly do -
BUT CANNOT for the life of m FIND THE TAXPAYER(S) THAT THE TAX NUMBER on the request belongs to!!!

Why does SARS not at least provide the NAME of the taxpayer in question - and at least a contact e-mail for
the requesting TP.

WHERE CAN I FIND ANY CONTACT DETAILS FOR REQUESTING TAX PRACTITIONERS???

Can anyone PLEASE URGENTLY HELP??

Thank you!
