Absa being useless. Again!

On Saturday internet banking and debit card not working. Called Absa, told my account on hold, Absa themself don't know why. Must call back on Monday. Monday internet banking suddenly works. Was told on Monday by Lebogang from complaints department (great service from her) that the hold has been removed, it was a glitch in the system and everything is working again (complaint reference number C-***8 has been closed according to Absa) On Wed and Thursday tried to swipe debit card and not working AGAIN. Called Absa, again told there is hold on account, they dont know why. They put me through to debt review who cant help because i am not under debt review. They put me through to credit card collections who cannot help because its not credit account on hold. They put me through to debit card collections who tells me its a glitch in the system and my problem is being escalated. AGAIN! 5 minutes from I owe money to glitch in the system. Absa has no idea what is going on in my account and meanwhile I should just be patient untill my account starts working again. How secure is my account if Absa themselves don't know what is going on with my account? Fed up!
