The Bank sucks n poor service from management and stuff

I went to Nedbank Tshwane Central today and i was assisted by Nini Wolf with staff number 208049 and i received a bad service, from the teller all I ever wanted was for her to check if the late had an account with nedbank so that they could provide me with a balance certificate of the deceased account but to my surprise she raised a quiry because Master of the High Court forgot to put n L on my surname n altered the L but surprisingly the very same letter i went to the Nedbank with i was assisted at Capitec, and Standard bank without any hussle and to make matters worse i waited for the team manager by the name of Glenda Morola and i was told that she was in the kitchen n i spent almost 30 Minutes waiting for her to come and assist me and sadly i had to leave the bank without seeing i wonder if we can't get help from managers where are we supposed to report urgent matters I'm not happy with the bank n I'm going to close my daughters account this bank sucks and ********* i won't recommend it to anyone.
