Incompeted service

On the 13 of May 2024 I updated my banking details and the consultant confirmed the change. On the 18 of May 2024 phone in for premium review, to my surprise the consultant (Zisanda) said my banking details still shows FNB. I requested the explanation and they said they would request a recording and send it me by Thursday (23rd) still no recording received. The banking details were changed and confirmed again. Today the Debit order bounced on my old bank. I phoned in today and Spoke to Seko she told me that the banking details were updated late. NO ONE TOLD ME THAT! I asked d to speak to a team lead and she told it’s only available at 10:30 and I said there should be someone else to talk to and she put me on hold for 2 minutes I had to drop the call. This is really upsetting, it seems like the consultant do not know what they doing.
