Unknown Monthly service fee on Standard Bank Account

I have been a Standard Bank client for more than 20 years. Unknown fees they charge these days, have me hot under the collar. I pay a monthly service fee. No problem. Jan 2024 an additional fee appears which is now levied for sms confirmation on card transactions. Something that was never charged before. Jan, Feb, March 2024 continue with a different additional fee each month, depending on my card transactions. April 2024 I contact Standard Bank. The consultant does not really know why this arrangement has changed. She mentions that "after December 2023 holidays when she came back to work, they were told the additional fee would be levied from Jan 2024." I cannot find any communication that this arrangement was communicated to me. I ask that this cost be disabled from my account, as I was under the impression it was part of my monthly fee. The consultant disables this fee and I no longer receive sms notifications on any card transactions. Literally the month after I cancel the above mentioned fee (May 2024), another service fee of R15.00 is levied. On 03/05/2024 I contact Standard Bank and ask what this is for. The consultant cannot answer me. Reference number *** and R15.00 is reversed. On 05/06/2024 I have to contact Standard Bank again as the R15.00 is once again levied. Reference number *** and R15.00 is reversed. Consultant does not know what it is for, but confirms that I can expect a call from Digital Banking with regards to the R15.00. I never get a call or communication. On 03/07/2024 I have to contact Standard Bank again as the R15.00 is once again levied. Reference number *** and R15.00 is reversed. Consultant does not know what it is for. I request the consultant to make a note on my account for Standard Bank to stop deducting this fee. Consultant confirms that I will receive 2 x emails from Digital Banking. I never receive any communication. On 06/08/2024 I have to contact Standard Bank again as the R15.00 is once again levied. Reference number ***. I notice that R15.00 does NOT get reversed. On 20/08/2024 I contact Standard Bank again. Consultant Tshepo confirms that he can see on the system that my request was declined. Consultant cannot tell me what this R15.00 is for. He puts me on hold and after 41 minutes and 19 seconds I put the phone down. Tshepo / Standard Bank does not phone me back, even though they called me after my 20/08/2024 contact and therefor has my number. No reference number. It is now 22/08/2024 and I have had no contact from Standard Bank. Please reverse the last R15.00 and stop deducting it on a monthly basis. I have no idea what it is for and by the looks of it, neither does Standard Bank. It is VERY coincidental that that this amount was never charged, but the moment I stopped the "per transaction fee" that was levied from Jan2024, Standard Bank started with the R15.00 fee.....
