***** case resolution not fully investigated

I had ***** transaction done on my nedbank account just before Christmas in 2022 and logged it with the bank then. Until 11 January Noone contacted me on the case. Called the bank on the 11th January and got the agent assigned to my case called Busi who never bothered to contact me. After calling the bank to get feedback on the 12th I was told that the case will take 45 days by a gentleman called Sifiso. He then advised me that he can expedite the case which on the same day in question my request was declined and am sure that this was done as spite and punishment for me for raising the complaint.
