Refusal to help then served with documents to reposses property

My mom passed away 6 months ago and had a home loan with standard bank, i went there to inform them to check for me what's needed what is the next step.. Standard bank the glen mall refused to help as she had a will and they wanted letter of executor, standard bank home loans has never contacted me.. But their lawyers has and now they have sent me a letter to reposses the house... I've been there countless of times ive called your deceased line which doesn't have an agent due to covid now because your people fail to do their job i must suffer 😠 am not getting statements, standard bank people are not helping they don't want to disclose what she had for how much.. You insensitive and useless
