No customer service, had to wait hours, only 1 consultant available

My mother passed away in Aug. I am the executor for her estate. I received my letter of appointment on 10 Nov. I went to ABSA Monument park to close her accounts. I was referred to the consultant Thandiswe. This was at 8.40 on 12 Nov. I have certified copies of all the documents. I was told that i need to produce the original documents as well, we went through the list, ID, J170, J85, my ID. ABSA bank does not accept the certified copies, done by Tshwane Trust in front of a Commissioner of Oath. I got up and went home to collect the originals. 8:45 I went back to the branch, 9:05. I had to wait till 10:30 as they only have this one consultant to assist, No body else available to assist and all the customer had to wait this long. I did try to find the Branch Manager, no where to be seen. This consultant told me that i also need the original death certificate. I did tell her that she did not tell me to also bring this document. She cannot assist me. When i told her that she DID NOT tell me to bring this document as well, she said i left before she could tell me. She did not make an effort to assist me from the start and i feel this is a ****** issue as well. I do not feel that she as an ABSA consultant, provided any customer service and to me she felt in charge because i am white, she can tell me what do to, and not tell me what do to and also do not assist me the way that she should have. To provide customer service, you look at what is needed, tell the customer the first time, this is what is needed from the bank requirements. When i told her that i am going to complain about this, she just laughed and indicated that it is not a problem and i can do whatever i want. This is also why i feel she wanted to show me she is in charge and unfortunately i cannot go anywhere else. This is pathetic customer service and i am a very unhappy person. What happened to ABSA bank customer service? Pathetic
