Useless ***** agents, Disgusting service

Yesterday my salary was paid in. Today, R11,000 is missing from my account. No transactions by me, just a gaping hole where my money should be.
I immediately contacted the ***** Department. Speaking to Miss Anthony and her Team Leader, I was told they "cannot see the balance" and, astonishingly, that "there is nothing they can do."
As a former staff member, I am intimately fami**** with your systems, your processes, and your escalation protocols. I know that ***** queries are supposed to be treated with extreme urgency to prevent syndicates from cleaning out clients' accounts. I know that balances are always visible to authorized staff.
To be told there is nothing you can do—and to have a Team Leader back that up—is not only a failure of process, but a shocking dereliction of duty.
Because of this inaction, my account is frozen in limbo. My debit orders are due to run. Because my balance isn't reflecting, those payments will fail. I will incur penalties. My credit record will be stained. All because your ***** Department refused to do their job.
If this is how you treat an insider who knows exactly where to escalate, what hope does an ordinary customer have?
I need this escalated immediately. I need my account sorted, my penalties reversed, and my records cleared. No one deserves this treatment.
