Terrible loss in our family …. ABSA no help

Good day My dad passed away on the 19th of May, I have called Absa, been to a branch and sent emails. Requesting that my dad’s account is frozen but I get zero communication. My dad was a customer at Absa for over 40 years, now when I need there assistance I get no help. Firstly, when I call to register the deceased estate I get told we are changing systems and I must be patient - no turn around time given. Secondly, no body calls to communicate or send me any forms to start the procedure Thirdly, my dads Will was at Absa so I am presuming they will handle the Estate and contact the magistrate to register the deceased estate I would really appreciate some guidelines and assistance / for a customer who was with you for over 40 years Not only do we have to deal with this heart breaking death but also trying to get answers out of anybody is exhausting Some kind words and feedback would make a huge difference in our lives Please can someone help and assist me
