Why is it so difficult to do change of signitories

Why is difficult for ABSA to do change of Signitories.....

I went to. ABSA to enquire or to do change of signitories. I went to the consultant by name of Slyvester who was so nice to assist..... unfortunately he wasn't our Banker, but he referred me to Jane on the system it shows as Jane is our Banker. I emailed Jane what we wanted to do, she rep**** & cc'ed Itumeleng as the person or the banker who's supposed to assist us. Unfortunately never responded to the emails, even after I sent him personally my email. Sylvester for being nice he gave me his number to contact him if I encounter any problems....then I contacted him to assist me in getting hold of Itumeleng. I WhatsApp Itumeleng, but his response it was after 5hrs, which means we going to communicate (respond) the following day. This led to delay 😠 and frustration. Because simple conversation took almost five days, only for enquiring about change of signitories. I lodged a complaint with ABSA to resolve this.... COMPLAINT – (C-***6 ), consultant Lerato called after three days when complaint was locked..... thinking she's resolving the issue, only to find later that she's the banker who's supposed to be assisting us with the change of signitories. She told me that someone from Soshanguve will assist us everything will be prepared for us, we just need to bring right documents & she'll sets appointment for us. On the day before the appointment, I collected to remind her of the appointment. She told me that the Banker is swamped & she'll call me to make appointment for another day. Then Jane called me whom thinking we are going to work with asking why are we refusing to work with our Banker & agreed to close the complaint when the matter is not resolved 🥺.... cause the Banker need to assist us to the tee. She needs to assist us even where we are in the city, since we are customer to the bank 🏦. But Lerato moved her responsibility to another Banker. Because she was unable to assist, she told that she isn't allowed to talk to me, she can only talk to talk to current signitories, which one of the signitories has passed on, others are pensioners hence we wanted to do change of signitories. Why is so difficult to do change of signitories with ABSA? No customer service.....
