Bad invasive service

I receive an sms from nedbank 08H15 today 6 February 2025 "Nedbank. Your financial well-being is important to us. Unfortunately, you have breached the terms and conditions of your Nedbank overdraft and we have reduced your overdraft facility. Call us on +*** to discuss your current account. No reply SMS" Wow what a shock for me to receive this sms as i have had this account from 1986 !When i phone Nedbank, after the 3rd transfer, the telephonist does not know what the query is after he checked their system and my account. No reference number available for my call in spite of being told the call is recorded, because i would request that the recording be traced to see the service i received on this call, and yesterday afternoon i receive a call from Nedbank, and on answering i get no response, Please Nedbank stop this bad sefrvice, and if look atmy history from different accounts you will note that every time i have to deal with Nedbank i have this kind of service problem, thank goodness for internet banking!
