Estate late department is useless, they add grief onto of the grief one suffers from loosing a partner

Very bad service, my mother hospitalized because of the stress they have caused her since losing my father in Novemeber last year, they do not give feedback will she is grieving she has to continuously ask for feedback and be sent from Pollard to post. Worse Estate late department is never available to assist her. We paid their remaining amount but to date we have not received any communication and they are still deducting money from my mother and they refuse to give us a settlement letter to give her employer. I logged a complained and till this day we still haven't received any feedback they keep saying they will call us to date still not feedback. They are causing my mother added grief. We just need to get this matter sorted once and for all. This is ****** nonsense lesson I would advice everyone to never do business with Nedbank
