Deceased Estate and shocking service

Dealing with Neo, in deceased estates has been utterly appalling. My father passed away in Jan 2018. ABSA was made executor as it was a small estate to wrap up. However, I have received nothing but radio silence from the group since Feb 2018. I am trying to claim commissions owed to my Father through his employer, and wrap up rental contract however it is IMPOSSIBLE to even get so much as a basic email reply from the consultant. Absolutely shocking
