ID number actually linked to (inactive) cell no NOT WALLET

I've been trying for months to EXPAND WALLET but the LEARN MORE says its UNDER REVIEW. ref: A3-BGEN-C7NUZ When trying to expand wallet to my current number I get the error: THIS ID NUMBER IS ALREADY LINKED TO A WALLET. CHANGE ID NUMBER !!!!!!

After eventually TALKING to someone, they insist that I have a wallet so I remembered that I must have expanded ON AN OLD, INACTIVE NUMBER. WHY DIDN'T VODACOM PICK UP ON THIS AND DEACTIVATE THE OLD WALLET ON A AN OLD (RECYCLED?) NUMBER.. I logged a call and its TWO DAYS and they still haven't unlinked the wallet. HOW LONG DOES IT TAKE TO UNLINK ?

NOTE : I was a senior manager at vodacom and mtn so know that this literally takes 15 minutes so its appalling service and I use other csp to load data so they lost money.
