Good payer /bad payer

It all started with a message on my WhatsApp stating that I'm in arrears on my account, I then went into my mobile app checked December 2024 statement and it showed I paid more then the minimum R330, I paid R500 for December 2024, now I get a message of demand that I'm in arrears, I have to pay R757. 93, I call the call center agent and she was of no help, I explained to her,the statement sent to me asked for December 2024 a minimum of R325 must be paid, I paid R500, she said but u purchased items after that, I said we'll then it should reflect on the January 2025 statement and we are only in the 15th day of January, so I still have time to pay, why must I get threatened to be charged extra if the month have not completed yet, she muted me, and wen I said hello is anyone there, thinking I lost connection, she sarcastically greets me like I'm stupid, I feel like paying my debt finish and closing this account, so much hate I have now for Woolworths
