Flabbergasted at agent's responses

I received a text message from Standard Bank saying my account ^^^^^^0494 is inactive. I queried this. I got a call back today. The agent could not tell me why I received such communication. She said "it might be". She said that accounts are dormant after 6 months. There was activity on mine a month or so ago. Please listen to the recording to hear that the agent cannot give me a valid explanation. If memory serves me correctly, I mailed a copy of the text message. Please investigate and revert with a definitive answer.
