Poor service

My recent dealing with Standard bank deceased estates department has been nothing less than frustrating to say the least. I have not been receiving updates from them, neither have I been able to ascertain information relating to my query. Emails not actioned timeously, lack of feedback, no communication even after escalating to management. Documents not sent for confirm settlements. Only time any information was relayed was when they submitted claim letters for outstanding amounts owed by my late dad. I am a standard bank customer for over 20 years and to think this is the level of service they provide is appalling. Seriously considering moving my business to another bank.
