Late Estate Account Closure

ABSA Please explain yourselves! My Mom passed away in May 2019, she had 2 accounts and a Credit Card with you. You were provided with the Death Certificate and Letter of Executorship by the beginning of June 2019. It has taken me until the beginning of September to close the 2 accounts by visiting ABSA Greenstone every Saturday morning since the beginning of August. As for the credit card - after numerous emails, and 100's of phone calls, I am getting nowhere! I have been given various numbers to call, been told to speak to Rosa or Lucy, on numbers that are never answered. Been promised by consultants that "someone" will come back to me. Which NEVER happens. The account was changed to a E/Late account, then this month I receive the statement and it's back to a normal account. You are quite happy to keep charging bank charges - but have no interest in assisting me. Even your case number sent to me via email means nothing!!!!! WHAT DO I HAVE TO DO TO SORT THIS OUT??????????????
