VIRGIN ACTIVE ******!!!

I received an email from Virgin Active, stating that my account is in arrears of R1346. I called the number provided because I needed clarity on this matter. According to my understanding, my contract was terminated in August 2021. They have been billing me all along. I spoke to Lubwe on 19 January 2022 at 16:54 and he told me that the arrears on my account are R961. Why is there a R385 difference between the amount given to me by the consultant and the amount sent to me via email? Secondly, why was my membership not terminated after the 24month co tract period? None of this makes sense, especially the arrears amounts that are being quoted.
