Out of bundle limit lock is not restricting my data usage

Good Day

The Vodacom Out of bundle limit lock is not restricting my data usage once the bundles have been depleted. I received a message from Vodacom informing me that I have used R50.02 on out of bundle data so far this month. I checked the out of bundle limit and it is set at R0.00.

I do not understand why data is being depleted despite this limit.

My efforts to reach a warm body through the customer service call center number have proved fruitless.

I would appreciate a response in this matter.
