Bad Bad service - Std Bank Funeral Plan

My Mother passed away on 30 April 2024 - we had a Funeral policy for Mum and Dad - Dad is still alive - we requested that debit details be changed - Std bank Funeral insurance has been requested to change the debit order details - we spent 4 hrs at the branch - we now learnt that Std Bank Insurance lost our information after we followed up as Std bank tried to debit the wrong bank account again - the Call centre is useless cannot assist - we need help urgently...
